I was unsure which section to post this in as it could be applicable to ‘issues while printing’ and perhaps ‘software issues’. Mods feel free to move if necessary.
I printed my first large part after completing my z-axis upgrade, and encountered a problem 2/3 the way through the print. Between layer 125 and 126 (0f 214) the printer detected a ( echo:endstops hit: Y:101.34 ) this caused the remaining layers to print about 30mm offset from the rest of the job, ruining the job, wasting 5hrs of print time, and 7mtrs of filament!
I spent all afternoon yesterday printing small test cubes and such, making fine adjustments to the newly installed z axis, and tweaking Repetier settings to fine tune overhangs. The printer never missed a beat. Print quality is much better after the upgrade, and now only a nozzle upgrade will allow me to improve further. I never encountered this problem prior to upgrading the z axis either.
Things I did that may have contributed to this false y axis endstop trigger. Due to additional electrical load on main board.
Increased z axis motor voltage to .55v (due to the new lead screw being 3mm pitch/extra load ect)
Over ride auto fan control in Repetier (fan now runs at 100% after the third layer)
Do I just put this down to a glitch? Do the endstop micro switches ever give issue? Could it be I’ve reached the limit of the standard power supply (motors set to .55v, fan on 100%, bed temp set to 60deg C)?
Please feel free to proffer some advise.
I plan on reprinting the failed part again tonight. After testing the printer today, checking all the wiring and printing several small test parts. I have to say the printer performs without fault. I’m loath to setup such a large print again without knowing the cause of the issue, and if it will occur again a cost me time and money.
Many thanks.
Justin.
