I to am interested with this. I have tested the backlash on all 3 axis. Z is about 0.025mm Y 0.03mm and X 0.05mm. Having done extensive testing and fiddling with the X axis. I can say it's not the preloaded thrust bearings. I tightend them and it mad 0 difference. I thought it might be magnetic back...

So changed the motors for nema 23 off the rack cheep as chips motors. Jobs not to bad. Just looking up the wiring to join. My x and y were not the motors that have been listed on here before. They were HY200 2220 0210 ACM8 These were 8 wire motors. They joined 2 sets to make it 4 wire. So it's dead ...

As it's a kind of ac motor I am gussing it's the same thing. It's just it does it when there is no good rea...

So I got my novamil all coverted to mach3 for a while. But I have been having trouble with the x and y. Especially the x. For no good reason it will stall. Not when ploughing through stuff but just when doing a move. I have decreased acceleration. Incread and decreased micro stepping. Same with amps...

Hi. After wanting a nice little CNC mill I happend across a Novamill at a very reasonable price. So I couldn't say no. Now it doesn't have the control box at all.
