After 2000+ hours the hobbycnc driver gave up the ghost. The Y chip decided it only wants to go in the plus direction even when jogged in the minus direction. It trashed a $75 piece of metal by drilling holes in wrong places. That's more than the whole cost of the driver! I'm going to order a G540 and eventually replace the chip on the hobbycnc board so I can use it for a smaller specialty machine I have planned for the future.
I got my money's worth out if it I will say that. Pretty happy with the performance until now. I highly recommend it for first time builders on a budget. The general consensus is if you use your machine long enough, eventually you will need to replace a chip.
