Hello, I have a lead 1010, worked ok for a while but the last time I ran a job, the tool plunged in way to much towards the end of the job. Since then I noticed the z axis is only working properly close to home position. If i go further than 300mm in X and Y from home Z goes to hell. Any ideas? Thanks!
Have you checked your wiring to see if maybe there is a loose connection or a short? Maybe when the wire is bent in a position other than how it is at the "home" position it causes a short making the motor behave erratically.
so you are saying that when the tool is moved 'far' away from home, Z acts weirdly. (knwoing exactyl what it does would help us analyse....) I see cable chains in your pictures. The Z cable is in that cable chain, maybe 2 of them. I think we can conclude that the motion of the cable in the cable chain, or near the ends where it flexes, might just be the problem. I would disconnect the Z cable from the blackbox (power off! ) and from the Z motor, connect a torch bulb so it is powered through that wire (1), then jog the machine around and see if the torch bulb flickers at all. I would do this using 2 pairs at a time, so 2 tests to check all 4 motor wires. (1) to do this I would put a jumper across 2 wires at the motor end then wire the torch battery and bulb to the other end, feeding throguh those same 2 wires. now the torch should be on all the time unless there is a problem with a wire as it flexes, jogging the machine around will flex the wires for us.
Hello David, Thanks for your reply. Yes, 2 cables in the chain, z motor and z switch. 4 cables in the chain to the side of the machine. I opened the chain with the 4 cables and looked at the z cable. I see lumps in it and when I move it by hand a little I hear the motor clicking like when I power up. I' ll find a new cable and replace it. Will let you know how it goes.
Eureka! It's working again. I cut the cable after the lump and wired it to the motor, I had extra length on this one. Thank you both for the much appreciated help!
