I reduced the feedrate for lifting in PrusaSlicer, but this left it stalling as it tried to start the print by traversing down 5mm again, I now realise that there is a maximum z speed setting, but the machine is not currently functioning at all.<br /><br />I tried updating the firmware for Marlin 1.1.x and set up all defaults suitably, but now whatever I do, whatever display settings I have, the display and the controller's encoder don't work.:S<br /><br />Also, the UART output is scrambled when baudrate is set correctly in Arduino IDE, and programs will not upload over UART, so it has to have programs uploaded over ICSP.<br /><br />The control board is an MKS Mini v1.2, there is 1 extruder, 1 fan, no heated bed is fitted on the machine, and 1 z-axis motor. The display is a Reprap Budget Smart Controller.<br /><br />Does anyone have the Sintron firmware or has anyone managed to setup Marlin 1.1.x for it, what changes must be made from the default configuration?<br /><br />I can't find the MKS Mini v1.2 in the available boards, and no settings I've tried seem to run the display.]]></description> <dc:creator>chris125</dc:creator> <category>United Kingdom RepRap User Group</category> <pubDate>Sun, 23 Jan 2022 12:55:16 -0500</pubDate> </item> <item> <guid>https://reprap.org/forum/read.php?53,887941,887941#msg-887941</guid> <title>Laser hook up to a ramps 1.4</title> <link>https://reprap.org/forum/read.php?53,887941,887941#msg-887941</link> <description><![CDATA[ My laser has 3 wires, positive negative and PWM<br />How are these connected to the Ramps 1.4 board.<br />Any advice appreciated, thanks]]></description> <dc:creator>jodougie2812</dc:creator> <category>United Kingdom RepRap User Group</category> <pubDate>Thu, 20 Jan 2022 06:17:23 -0500</pubDate> </item> <item> <guid>https://reprap.org/forum/read.php?53,879077,879077#msg-879077</guid> <title>Pertinax permanent printing plate</title> <link>https://reprap.org/forum/read.php?53,879077,879077#msg-879077</link> <description><![CDATA[ Hi guys,<br /><br />I have read in several forum posts that Pertinax is excellent as a permanent printing plate.

This was given to me in a slightly ‘used’ condition with the lcd screen showing two parallel bars.<br /> I’ve managed to use the ‘blink’ facility on arduino IDE and I’ve located the hephestos firmware on Marlin as I assume it’s that part that’s in need of reloading.<br />I’ve assumed that as I’ve been told a previous attempt at renewing the firmware failed. Hence the LCD display as described. <br />So my problem is trying to load the config h and config avh into Arduino IDE, I keep looking for a marlin.ino or pie file iwithin the zip file.

The power supply began to pulse at about 1hz. After this mistake, the Ramps board has stopped properly connecting to my laptop running repetierhost via USB. Repetier respondes with this error message: Communication Timeout - reset send buffer block. I can successfully reflash marlin onto it and flashing another example code I can see that the arduino can use serial communication. My full graphic discount smart controller outputs only white, I've tried changing the contrast on it but there is no display output. I've checked the voltages and there is definitely 12v (ps_on pin moved to a ground pin) and 5v output. There's no visible damage on the ramps board or the arduino. The connection to the arduino seems to work better when the display is not attached but still is patchy. I was able to read the thermistors for the extruder and the heated bed but only when they were switched, I was also able to heat the extruder when they were switched, which should have thrown an error and has in the past when the PSU isn't on.<br />Any help would be greatly appreciated.<br />Max]]></description> <dc:creator>maxba</dc:creator> <category>United Kingdom RepRap User Group</category> <pubDate>Fri, 26 Jun 2020 10:06:18 -0400</pubDate> </item> <item> <guid>https://reprap.org/forum/read.php?53,866708,866708#msg-866708</guid> <title>Duet3D wifi remote control</title> <link>https://reprap.org/forum/read.php?53,866708,866708#msg-866708</link> <description><![CDATA[ Hi everybody, I'm currently working on my self-designed coreXY and I will use the duet wifi as mainboard. I got some questions about it:<br />- i will use 2 different PSU, one for the hated bed and one for the board itself. the big one ( heated bed ) will supply the 5V to the duet when turned off the 24V via SSR. I studied the wiring diagram and I end up with this configuration: heated bed's PSU feed 5V via 5V pin next to the PS ON pin, the other pole connected to the GND pin on the other side of PS ON. PS ON connected to the SSR negative pole and the positive one connected to the 5V pin in the expansion board. ( the SSR control the board's PSU). Is it correct the wiring ? (I don't want to blow up my new duet)<br />- if I get it right, I understood that the Due Web Control can turn off the printer through the PS ON, opening the SSR circuit and cutting the power provided by the PSU's 24V. But can I turn on the printer via Web Control ? I mean, the WC I always accessible despite the printer is on or off ? using the WC I assume that I can control the "standby" part of the duet (the one supplied with the 5V) and it will close the SSR circuit repowering with the 24V the board (turning it on). did I get wrong something ? are my interpretation correct ?<br />thanking you in advance !!]]></description> <dc:creator>JackTom2098</dc:creator> <category>United Kingdom RepRap User Group</category> <pubDate>Tue, 28 Jan 2020 09:34:24 -0500</pubDate> </item> <item> <guid>https://reprap.org/forum/read.php?53,862732,862732#msg-862732</guid> <title>New extruder for Anycubic mega s over extruding</title> <link>https://reprap.org/forum/read.php?53,862732,862732#msg-862732</link> <description><![CDATA[ Bought an Anycubic mega S printer - [<a href="https://www.anycubic.com/products/anycubic-i3-mega-s?variant=30151498367036" target="_blank" rel="nofollow">www.anycubic.com</a>] and decided to change the extruder. <br /><br />However, the new extruder <br /><br />[<a href="https://www.amazon.co.uk/FYSETC-Extruder-Long-Distance-Filament-Creality/dp/B07S7C4T7Y/ref=asc_df_B07S7C4T7Y/?tag=googshopuk-21&linkCode=df0&hvadid=372372480883&hvpos=1o1&hvnetw=g&hvrand=10004288099756258047&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9046040&hvtargid=pla-791140123834&psc=1&tag=&ref=&adgrpid=76472267756&hvpone=&hvptwo=&hvadid=372372480883&hvpos=1o1&hvnetw=g&hvrand=10004288099756258047&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9046040&hvtargid=pla-791140123834" target="_blank" rel="nofollow">www.amazon.co.uk</a>]<br /><br />FYSETC 3D Printer Upgrade Extruder Long-Distance Remote Metal Extruder Right Hand Block Kit Spare Parts 1.75mm Filament for Creality Ender 3 CR-10 Prusa i3 Anet A8 Anycubic Mega Wanhao i3<br /><br />Has no offset gears which means it’s now a direct feed - over 50% faster.

I have the 220 x 280 bed size and this is defined within the firmware I am running (The latest Marlin from here [<a href="https://github.com/JimBrown/MarlinTarantula/" target="_blank" rel="nofollow">github.com</a>]). <br /><br />When I auto home the print head the nozzle sits in the front left hand corner however I have noticed that the print head is 24mm towards the right on the x axis (this is obviously part of the design) so I thought that by entering the following into the firmware this may resolve it <b>#define X_HOME_POS 24</b> however it appears to have no effect on where the printer starts.<br /><br />The front of the calibration cube is started at 139mm from the front of the build plate and the start of the edge is 124mm from the left side of the build plate, <br /><br />I have also uploaded a picture here <a href="https://www.dropbox.com/s/hepm8v2km42iow9/IMG_20171126_190111.jpg?dl=0" target="_blank" rel="nofollow">Image</a> so this can be seen a little more clearly (file was too large to attach here).<br /><br />I have also uploaded a copy of my configuration.h file here <a href="https://www.dropbox.com/s/k0r8qj7hhizoan3/Configuration.h?dl=0" target="_blank" rel="nofollow">Configuration.h</a> if anyone could take a look and help.<br /><br />Is anyone able to tell me how to resolve this as I really like the printer but this one small aspect is bugging me and I don’t know how to solve it/<br /><br />Thanks everyone for your help.<br /><br />Noel]]></description> <dc:creator>noelmm</dc:creator> <category>United Kingdom RepRap User Group</category> <pubDate>Sun, 26 Nov 2017 14:37:47 -0500</pubDate> </item> <item> <guid>https://reprap.org/forum/read.php?53,797836,797836#msg-797836</guid> <title>And this connects to......</title> <link>https://reprap.org/forum/read.php?53,797836,797836#msg-797836</link> <description><![CDATA[ Hi, I'm new to the Rep Rap community and am building a Makibox 3D kit that was offered about a year ago. I was doing OK despite the woeful "instructions", but I am stuck on a connection to the PCB. From the Extruder head I have a green and a black wire from RT with 2 pin plug attached. On the PCB I have 3 sockets :- 1) FAN / J14, 2) HE TH / J12, 3) HB TH / J13. Anyone out there successfully built the kit and could give me a clue ?]]></description> <dc:creator>Marshallmaker</dc:creator> <category>United Kingdom RepRap User Group</category> <pubDate>Fri, 24 Nov 2017 16:14:51 -0500</pubDate> </item> <item> <guid>https://reprap.org/forum/read.php?53,758399,786222#msg-786222</guid> <title>Re: Problem with the A4899 drivers</title> <link>https://reprap.org/forum/read.php?53,758399,786222#msg-786222</link> <description><![CDATA[ Try disconnecting the pin.

Using Pronterface, I can check the axes move the extruder and heated bed in the direction I'd expect and the hard endstops work correctly. Using Slic3r to generate the gcode, the code looks right, however, when it gets to the first G1 Z0.2, it sends the print bed all the way down, beyond (if it could) the bottom of the printer, causing the z axis stepper to complain bitterly. In fact if I remove the first G1 Z0.2, it happily prints the first layer (albeit very thin as the bed is still at 'home' ie not 0.2mm lower), then as soon as it gets to the next G1 Z, it send the bed all the way down again,<br /><br />To get the printer to home in the right direction, I've changed the X, Y and Z_home_dir to 1 and so am using the max hard end stops. Here's a snippet of the configuration.h code so you can see;<br /><br /><br />// @section homing<br /><br />#define Z_HOMING_HEIGHT 0 // (in mm) Minimal z height before homing (G28) for Z clearance above the bed, clamps, ...<br /> // Be sure you have this distance over your Z_MAX_POS in case.<br /><br />// ENDSTOP SETTINGS:<br />// Sets direction of endstops when homing; 1=MAX, -1=MIN<br />// :[-1,1]<br />#define X_HOME_DIR 1<br />#define Y_HOME_DIR 1<br />#define Z_HOME_DIR 1<br /><br />#define min_software_endstops true // If true, axis won't move to coordinates less than HOME_POS.<br />#define max_software_endstops true // If true, axis won't move to coordinates greater than the defined lengths below.<br /><br />// @section machine<br /><br />// Travel limits after homing (units are in mm)<br />#define X_MIN_POS -46<br />#define Y_MIN_POS -11<br />#define Z_MIN_POS 0<br />#define X_MAX_POS 215<br />#define Y_MAX_POS 134<br />#define Z_MAX_POS 140<br /><br />I appreciate that there must be a lot more information you might need to help diagnose the problem, but as I'm a stumbling newbie, I'm not sure what that might be. Just met me know.<br /><br />Thank you for your thought cycles.<br /><br /><br />Andy]]></description> <dc:creator>pintokitkat</dc:creator> <category>United Kingdom RepRap User Group</category> <pubDate>Fri, 16 Jun 2017 13:42:43 -0400</pubDate> </item> <item> <guid>https://reprap.org/forum/read.php?53,421928,767992#msg-767992</guid> <title>Re: How did you get started?</title> <link>https://reprap.org/forum/read.php?53,421928,767992#msg-767992</link> <description><![CDATA[ Have been running a 'Prusa' P3 Steel for the last 2 years. The P3 Steel frame was a great investment, so rigid and well made. Changed stepper motors a few times, definitely worth getting the most powerful versions that you can afford, my first ones were only 400mA rated and gave a few problems driving the Z screws properly.<br />RAMPS board has been reliable as long as cooling is applied to the DRV8825 stepper drivers. Regularly run for 4 hour+ prints weekly and still gives great results. Buy the bits from wherever suits your pocket.<br /><br />Not a kit but separates mainly from Chinese sites.]]></description> <dc:creator>FunBogMan</dc:creator> <category>United Kingdom RepRap User Group</category> <pubDate>Sun, 14 May 2017 14:54:19 -0400</pubDate> </item> <item> <guid>https://reprap.org/forum/read.php?53,761531,761531#msg-761531</guid> <title>Printing starts too high Prusa i3 Tarantula autolevelsensor</title> <link>https://reprap.org/forum/read.php?53,761531,761531#msg-761531</link> <description><![CDATA[ Before printing starts height is ok.
