General Mach Discussion / Z axis loss of cutting depth after multiple Z movements
« on: December 13, 2017, 11:52:35 PM »
Using Mach3 and G540. V carve cutting depth set at i.5mm. Series of text around a 475mm dia curve. At the end of the cut the tool is 2 mm above the material. Settings are from top of material.
Tried Z setting from top and bottom of material both of which show the same problem. Table is and material are perfectly flat. Tool is tight. No back lash. slides are clean ,lubricated and are not binding.
Have also a series of intermittent stops which seem to be getting worse. Suspect the G540 Bob is the cause. Have 4 Leadshine Microstep drivers DMA860H, power supply and ample wiring.
Was thinking of ditching the G540 and buying a ethernet BOB. The prices of the Smoothstepper are clearly excessive and beyond my means. The only BOB of reasonable price is the NVEM which claims mach3 compatibility but speaking to mach support they have never tested or approved this BOB.
Can anyone shed light on the Z axis problem and if the NVEM works with Mach 3. Is there a ethernet bob of reasonable price and proven use with Mach3
