Hi again.
So I just managed to fit the new pc, and I have no idea why, but it works perfect. No stalling or jerking at all. It.s a single core celeron, 512mb of ram :)).
I have to complete a woodworking order these days, and then, I.ll have time again to continue the cnc.

Just to have something to think about meanwhile, what comes next?

Point 1: I.ll mention again the vfd problem, as I guess I have to figure this out to.
I wired up the vfd, I change Parameter 1 and 2 to value of ..2..(for communication port control), then wired the 4 control wires like posted before ..the gnd pin goes to ACM, the 0-10v to V1, 1st relay pin (5th in order) to DCM, and 2nd relay pin to FOR., and then in mach 3, in motor outputs, I enabled the spindle, step pin 1, dir pin 0, dir lowactive and step I tried in all ways, step port and dir port both to 1, then in output signals I enabled output 1, port 1, pin 17, active low not checked, then spindle setup, relay control with disable spindle relay not checked, motor control with ..use spindle motor output.. and ..pwm control.. both checked and pwm base freq to 100, then in spindle pulleys, nr1 max speed 24000.
And it does not work. It does nothing when i press spindle cw f5, although the relay clicks on, and the voltage at terminal 0-10v is 9.54v The vfd just shows 0000000 on the screen.
What have I done wrong?

Point 2: I.ve made a 130cm/130cm solid wood table top to put on top of the metal structure. I was thinking to mill this flat, and add over an particle board or some sacrificial board. I don.t know how to mill it, but that.s the plan.

Point 3: It has been mentioned in this thread to add the vfd somewhere outside the control box. Sometime in the near future, I.ll get a dust exctractor thing, but right now, it.s a mess in there, and lots of fine wood dust all over. Have anyone used a vfd in this kind of conditions? Is it a high change of breaking it?

Point 4: The ballscrews and linear rails seem to cope ok with the fine dust. I.ve read some time ago that this systems need some extra lubrication even if they have some of their own when they get out of chinese factories. Any suggestion? Please don.t say grease.

Or the initial question: Now that it works, what comes next?
