Mach 3, Erroneous movement in Z axis
« on: April 27, 2021, 01:43:36 PM »

I have a Small CNC rOUTER 60 X 60 CM.

Last days , Iam having a problem because Z axis sometimes is moving different distance that G CODE
Yesterday G zode indicate move from  Z-3 to  Z-6 and Z axis make a momement to z-11. (Look the picture).

I stop the Job and restart again from 100 lines before using Run from Here but some part of the job was ruined.
Area in Red contour in Picture 2

Other times the gcode indicate to move G0 Z20 for save heigh and move 1-2mm and cut inside the job

Iam thinking the cuold be a interference caused for electrical noise..

Iam usiing a Hobby CNC Pro Controller.

Stepper wires are unshielded

I have a Cable chain and inside are running
X Axis Stepper Motor conductor
Y Axis Stepper  Motor conductor
Router AC supply conductor (Makita 1Hp Router)

That failure is ocassionally. Yesterday was 1 time in the day and later was working for 5 hours withput problem.

iam thinking to take out of the cable chain the Z axis stepper motor conductor and leave it hanging outside the machine
away of other conductors.

Could you help me please?
