I have had my pro a couple of months and it’s been doing its job OK. I never managed to get the x gantry to square properly with the endplates but I wanted to get cutting so ignored it. I thought I’d try again to get the machine properly squared so I’ve disassembled it and armed with two months of CNC knowledge I’ve tried again.
I’ve stripped the machine back to the four aluminium crossmembers and removed the belts. I have also removed the black support panels which, frankly, seemed incredibly tight between the front and rear endplates. I removed all the screws holding the y rails to the aluminium crossmembers and re-snugged and backed them out. I have also tried loosening the x gantry bolts to get a bit more flexibility.
I get the gantry square, tighten the bolts as per the instructions and a gap of between 0.004 inches (0.1mm) and 0.014 inches (0.35mm) appears between the left front y rail and the right rear y rail. If I pull the gantry forward to close the gap and then let go, it springs back to reveal the gap again.
The instructions say that there should be no gap and looking at the way it’s built, I can believe it should be pretty much self-squaring.
I’ve tried pulling opposite corners together using rope as per a forum post. Tighten the bolts and let the rope go and it’s unsquared again. Can anybody provide any advice while I wait for a response from the support team?
