Hello,
I recently got a Chinese 6090B variant machine from CNC-Warehouse, they call it the CM-6090B. It has a ~24" x ~36" x ~6" working area and a 2.2kW spindle with a Fuling 2.2kW inverter.
It has a parallel port BOB that can be seen here (
http://www.automationtechnologiesinc.com/products-page/breakout-boards/kl-db25rs).
The Stepper controllers are Leadshine M860's. It is a three axis machine, although I have a rotary that I will eventually set up as the X axis when using it.
I have spent a couple of days getting familiar with the machine & Mach3. So far I have the X,Y,Z axes moving; the home switches (proximity) trigger properly.
I have a few issues that I cannot seem to work out before I can go any further.
1) When I try to ref all home, the Z axis references first. It stops just past the home switch after it activates it, but does not back off until the switch turns off as I thought it was supposed to.
Then, the Y axis tries to home. It does not move- but the DRO coordinates for the axis show that Mach3 thinks it is moving. I can ref home the all axes individually. However
if the X or Z home switch is active the Y axis will not move. I have to back off the X & Y axes to turn off the home switches before Y will move. I haven't figured out why.
2) I have not been successful in getting the spindle to operate. Probably misconfigured (I hope), but I am sure it is wired correctly.
BOB has four wires to spindle; GND, SPEN, GND, 0-10V connected to DCM, S1, ACM, V1 on the Fuling VFD in that order. The Mach3 setup is confusing me.
3) I cannot determine the Stepper models, the labels are unreadable except I can just make out "450A". The M860 driver is factory set at 5.83A peak, 4.16A RMS.
The steppers seem to be working OK, but I don't have enough experience to tell for sure. Like, how
long should it take for the axes to travel the full table, what they should sound like, etc. Do I need to know the model #s for anything?
4) In motor tuning, I set the "Steps Per"...
X- 3/4" ballscrew @ 10mm pitch (.3937") @ 2.54 rev/inch x 200 step/rev x 8 microstep = 4064.008
Y- 3/4" ballscrew @ 10mm pitch (.3937") @ 2.54 rev/inch x 200 step/rev x 8 microstep = 4064.008
Z- 1/2" ballscrew @ 5mm pitch (.19685") @ 5.08 rev/inch x 200 x 8 microstep = 8128
Velocity
X- 196
Y- 196
Z- 98.425
Do these numbers look right?
The machine was supposed to come with a USB controller. Should I switch the parallel out to a USB?
I have attached my XML if you have time to look at it.
I would appreciate help, this is unfamiliar to me, especially the many settings in Mach3. I did not think I
would be jumping into the guts of this stuff just to get it to work but that's how it is going.
Thanks!
