Hello, I just finished building my new Lead 1515. However I am having trouble with the GRBL setting. When I choose Openbuilds LEAD 1515 my NEMA 23 2.45 high torque motors jump and lock up. This happens on the Y and X axis. Y1 and Y2 get out of sync and are not aligned. The Z seems to work fine in both setting. The X does the same as the Y. When I use the setting Openbuilds C Beam XL they seem to work fine but maybe a little loud. Hoping that someone has experienced this and has a clue what could be causing this issue. Thanks in advance for helping with this. Regards, Jim
Recheck wiring, if only 3 of the 4 wires are making contact, you see symptoms like that. See docs:blackbox:faq-identify-motor-coils [OpenBuilds Documentation]
Hello Peter, I should have put that in the thread but that is one of the first things I checked. However, I will do so again. Any other thoughts as to what may cause this. Regards,
Hello, Thanks for your suggestions. I still cannot find a problem with the wiring. I am using 22 AWG 4C Shielded Type CL3P/PPLP. It looks the same as the wire on the NEMA's. Could that be a problem. I was told this wire should be enough for these NEMA's. Hope that was correct. I can send images of my wiring from NEMA's to the blackbox if that would help. Regards,
Did you confirm both coils are wired correctly as per the procedure i linked above? If you are using 3rd party wiring, any other components from 3rd parties (not openbuilds parts) as the profiles are optimised for our parts.
Hello Peter, Sorry I am new and do not see a link you posted. Can you recommend the type wire I should order from open builds for a Lead 1515 using NEMA 23 2.45 high torque. Regards,
Here is the link for identifying motor pairs. docs:blackbox:faq-identify-motor-coils [OpenBuilds Documentation]
what is the different in max speed and acceleration settings between Lead1515 and C-BeamXL ? LEad1515 3500mm/min and 350mm/s/s C-beamXL 1000mm/min and 100mm/s/s So maybe the Lead settings are just too fast for the motors?
Hello, I have made progress. I changed the settings on Openbuilds LEAD 1515 to the following settings. $110 and $111 were changed from 3500 to 2000. They now work great. That brings up 2 more questions. Will it move slower and do you think the NEMA motors are not compatible? Regards,
If you could provide a spec sheet or a link for the stepper motors it would be tremendously helpful. Thanks.
Hello, Here is the link for the stepper motors. https://www.makerstore.com.au/product/elec-nema23-635-ht/ Regards,
I have a freshly assembled 1515, and I had a similar issue. My solution didnt find the exact problem; I put new ferrule terminals on all wires, and replaced the y1 + y2 wires (my mistake) Runs perfect- Just need to learn the programs
