MPG not working and DMM Zaxis faulting
Posted: Fri Jun 18, 2021 1:31 pm
Hi everyone,
Thanks for reading, we're having a number of issues getting this custom built cnc machine operating smoothly.
Item 1- Can't get the wireless MPG working, it seems to have wireless connectivity as it shows the icon in the top corner but in the CNC12 software the MPG led will not illuminate. I've followed the steps in the manual and I think I have everything configured correctly.
Item 2- quadrature errors on all drives, x,y, and z. For now they are being ignored and the machine seems to run fine. I'm not clearly understanding how the Centroid and DMM are interacting. Do these errors even matter? If I understand correctly, the DMM drive is closing the loop on the position, not the Centroid software so I don't understand why the Centroid is even paying attention to the encoder. I would think it should just be listening for a fault from the DMM but like I said, I don't clearly understand the relationship these devices have.
Item 3- DMM Drive Z has been faulting out. 95% of the time the red and green led drive lights are lit solid, no flashing. I have seen the lights flashing but I have no idea what the patterns mean, I can not find a list of flash codes. Using the DMM provided test cable I can connect to the drive and read the faults. Usually it says on position, but it has also said lost phase and over heating(can't remember exact wording).
So a bit about our machine, we are using 1.3kw DYN4 drives, we have one zaxis with a 5:1 gear reduction and electric brake. Our Y axis is a single 1.3kw motor with 3:1 gear reduction, no brake, and our x axis is two 1.3kw motors with no brakes, they are coupled in the software.
Our gantry is rather large and sees very little load, this is setup as a 3d printer so there is mostly inertia and it's own weight to overcome. The payload on the Z axis is roughly 10-15kg.
