  • Ok, just to sum up. That didn't do it (printing with SD card disconnected). Changing thermistor didn't do it. Changing RAMPS didn't do it. Changing MEGA didn't do it. I'm starting to think it is the extruder motor that has a problem sending out inte…
  • Hey, I don't know if this adds value to the problem solving or if it is a different problem (maybe just my problem really). But I found that my rapid temperature fluctuations, which are clearly not physical, appears in a somewhat systematic fashion:…
  • Ok, it happend again now and this time I have a log  - You can see I just upped the speed radically and then it stops: 22:09:34.966 : N24160 M220 S300 *6622:09:36.497 : N24161 M27 *5422:09:38.813 : N24163 M27 *5222:09:41.147 : N24165 M27 *5022:09:43…
  • I don't have those logs (I think).  I did not write a log file.  I usually put my PC to sleep after I start a print, I don't remember if I did that yesterday when it failed.  I think I must have done something, because the first log I have in my cur…
  • I just got it again. I was running from SD card ( but with host connected). This is the log: At 19:45:01,  3 and 6 I try to manually extrude and nothing happens. Then as I enable and disable it comes back alive.  19:44:51.723 : N1980 M27 *619:44:52.…
  • Hi,  I just wanted to put in, that I was experiencing the same problem. The extruder motor just stopped turning randomly on my newest printer. This is my 3rd printer and 2nd CoreXY and never seen that behavior before. I came to this post last night …
  • Maybe you can show a photo of the printer, the controller and paste the content of "configuration.h" 
  • Hello Did you ever fix this? Try the following - Set the printer z-height to something like 10 mm less then actual bed height (rough measured with meas tape). If the home position to z table is measured to maybe 80mm you need to put z height to 70 i…
  • Hi i follow the video you post up , everything good till after the  measure Heights in Measure Heights i use 7x7 pt so i use G29 , but i got 3 point only , how do i  get 7x7 point Zcorrection? Are you sure that you, when you downloaded the firmware,…
  • I think you should paste the log. 
  • Oh and... M502  - Reset all settings to the ones in your config. It gives me peace to do this every time I upload new firmware - Then you are sure the EEPROM is not messing with you. And: M322 S3 ; Reset auto level matrix permanently I know I wrote …
  • Hello,  The following is my (limited) experiences from aligning: Z length  
  • Hello Mattr254, That was a good idea. I tried that. It seems the holding torque is about the same then what it used to be. I did obviously not try to move the the carriages so much while my printer was working so hard to tell. I can just lift the co…
  • Hello kreto Just wanted to say thank you. Swapping to E1 (by downloading with the firmware configurator for that) did it finally for me. I still don't know whats wrong with E0. I tried to put a scope on it and I have no signal out ,so I am guessing …
  • Hello all, I just wanted to say that I have the same problem with the new firmware. S302 S1   does not work. We clearly need an unconditioned command that will move extruder motor regardless of cold, hold, dry-run or what ever other conditions. For …
