Re: Reprap stops mid print - help please anyone - 11 years ago
Thanks for that hint kevbme. Obvious when you think about it, but no I havn't. On another note, the cpu upgrade (and Marlin upgrade) seem to have made a difference, although it may still be too early to tell. At least one long print job is done without issue. And I've added the LCD and panel now. Get another roll of filament today and we can test some more of those large jobs.by maxaha1 - Reprappers
Re: Reprap stops mid print - help please anyone - 11 years ago
In the last few days, I have upgraded the Sanginololu board to as 1284p cpu and loaded all the latest marlin firmware from github. We'll see if the problems persist. One thing interesting though - when I pulled out the CPU to change it, the jumper to disconnect the USB reset was not actually removed. Seems that the cheap jumper on my board dissassembled itself. I pulled out the plastic part andby maxaha1 - Reprappers
Re: Bed Auto Leveling.. check this out - 11 years ago
So - this looks great. I'm dead sick of leveling the bed. Some PLAs its not so critical, but I;ve got this green stuff that that doesn't stick unless the bed temp and Z height from the bed are spot on. As well, the springs and screw adjusters seem to vary a little over very long prints where there has been lots of vibration (high speed hex infill for example). Anyway, I upgraded the Sanguinolby maxaha1 - General Mendel Topics
Re: Reprap stops mid print - help please anyone - 11 years ago
Well, battery backup is now installed. I can cut the main power for a few seconds without issue. But the printer still stops mid job. (Was printing from the PC though, not SD). Printer seemed unresponsive after the stop. Needed a reset to get working again. Will try again on SD. Anyone know how to JTAG these Sanguinololu boards ?by maxaha1 - Reprappers
Re: Reprap stops mid print - help please anyone - 11 years ago
Thanks for the hints both. So, the print head was still in touch with the job where it stopped. My default slicer settings used to home the X axis after a job, but on tall jobs it always crashed. So we have changed this to a Z+5 (relative mode) at the end and switch off the heaters. In the few cases I had recently, the head was still hot and touching the model. Anyway, some progress has been maby maxaha1 - Reprappers
Reprap stops mid print - help please anyone - 11 years ago
Hi All. Been printing now for about 12 months. Always had some occasional stops mid print. Installed SD card reader and printing from SD was reliable until about 2 weeks ago. As far as I'm aware, nothing changed in my setup. I dont think its overheating. Have printed much bigger jobs before and the drivers and motors are fine to the touch. Besides, there's nothing in the pololu to feedback errorby maxaha1 - Reprappers
