I ordered and put together the Lead 1515 machine for my workshop and I am running into a common problem documented in the forum. I have completed several projects but from time to time one Y Axis will stall while the other keeps moving. This only occurs while running a toolpath and not while jogging the machine. I have followed all recommended mechanical fixes, so I assume the problem lies in the grbl settings. (Which I am still learning). I attached my current grbl settings below and looking for anything that looks out of ordinary or suggestion numbers for correcting the issue. The grbl settings were downloaded from the default control software program. I made no adjustments. Thank you. $100 X-axis steps per millimeter 198.109 steps/mm $101 Y-axis steps per millimeter 198.109 steps/mm $102 Z-axis steps per millimeter 199.100 steps/mm $110 X-axis maximum rate, mm/min 3500.000 mm/min $111 Y-axis maximum rate, mm/min 3500.000 mm/min $112 Z-axis maximum rate, mm/min 1000.000 mm/min $120 X-axis acceleration, mm/sec^2 350.000 mm/sec² $121 Y-axis acceleration, mm/sec^2 350.000 mm/sec² $122 Z-axis acceleration, mm/sec^2 350.000 mm/sec² $130 X-axis maximum travel, millimeters 1180.000 mm $131 Y-axis maximum travel, millimeters 1270.000 mm $132 Z-axis maximum travel, millimeters 90.000 mm
1) check Grubscrews on shaft couplers (could be slipping of shaft coupler) 2) check leadscrews, binding could cause stalls (apply dry/PTFE lubricant if needed) 3) check wiring: intermittent loose connection does about the same docs:blackbox-x32:faq-identify-motor-coils [OpenBuilds Documentation]
and clean the rails/wheels and leadscrews of any dust and debris from previous cuts. the wheel rail interface is pretty tight so any lump of dust can look like a mountain in terms of increased rolling resistance.
Thanks for the info. I have cleaned everything up, sprayed dry lube, checked all the wires and grubscrews, and it is running a little smoother. Just making sure if I start adjusting the default speeds in the grbl settings I am not going to mess something up...
If you are using our profiles, the defaults we provide for our machines are well balanced (performing well, but still reliable). Whenever you plan on changing from that, there is always the chance it can be set to fast, so you probably are going to mess up. Backup regularly! Then you can always go back to what worked
