Yes, that is a possibility, TPS, but I'm quite pedantic with my processes and check, and double check, each step to be taken. I'll go through all the wiring again to make sure it's correctly soldered and connected to all the components. Thanks for the microstepping info, I've entered the new figures and motor smoothness has definitely improved.

I'll check the gantry drive train for looseness to reduce noise further, MN300. Just one question: could the anomaly in 'Motor Outputs' (having the Y Dir Low Active ticked but the X and Z crossed) cause problems at a later stage when I'm running code?

With Christmas almost upon us, I'll wish you all and your families a fulfilling and enjoyable time and a great new year.

I'm going to sign off now for a month or so to prepare for and share time with family, and to play with and go through the CNC work done so far with a fine tooth comb.

Thanks for your help TPS and ZASto, and for all the work you have done MN300; I could not and would not have done it without you.

Connect again in the new year. :)

The Y axis reversed its motion this time.
I now have the X and Z 'Dir Low Active' crossed and the Y 'Dir Low Active' ticked to run the axes in the right direction.
TPS, could this be a Mach3 software issue? It's not a wiring issue; might the TB6600s make the change?

The X and Z motors have quietened on the microstep 4 setting whilst stationary. The Y motor is noisy. I'll see what the situation is if I revert back to the last microstep setting.

It's getting dark, so Ill adjust mm/step and acceleration, and test microsteps tomorrow.

The switches are well marked and the states, and their switch positions, very visibly printed on the TB6600 casing. I'll change microstepping to 4.

I'll 'untick' and therefore 'cross' the 'Dir Low Active' boxes of all 3 axes to reverse their direction.

Turned the system on again after the last post and the Z axis is also reversed. I must have dropped my attention the last time or can the software reverse the Z direction to normalise Z motion with that of the X and Y axes? ???
The motor noises have reduced somewhat but the same frequencies are still there.

Thanks for the info

I set the TB6600 current switches to 1 Amp and connected cables to motors one by one, and tested for function and effect before connecting the next one.

All motors jog; the motors and gantry are quite noisy. I'll clean and grease the rails and Z Axis gantry v joints to quieten them but I think most noise comes from the X and Y motors.

X motor - direction is reversed, the motor emits a fairly loud beacon type signal when stationary and is warm.
Y motor - direction is reversed, it emits the same signal but not as loud and is also warm.
Z motor - direction is correct, it emits a soft very high frequency signal and is as cool as a cucumber.

The system requires fine tuning; where to from here?

That's good, so in my case it's 'Output Signals' - Output#1 - enabled is ticked - Port#1 - Pin number 17 - Active low is crossed; one output only ....Output#1.

Question - do the pins 1 to 17 that are printed on the BOB correlate with the parallel port pins? Also, the BOB Pin17 seems not to be connected to anything, so what is Output#1 used for?

I received the cable this pm, made the harness and attached it to the motors. I'll connect it to the TB6600s tomorrow, turn it on and hope smoke is a past experience.

Thanks TPS, copied it to the CNC profile in macros and entered the script. Output 1 responded by flashing the LED in 'Diagnostics' with the P1Q1 code. P2Q1 had no visible effect anywhere in 'Diagnostics'.

Would I be correct to think that the Q1 and Q0 of the code designates the On or Off state of the output; so would I be right to think that P3 would designate the 3rd Output? Or do they designate the BOB P2 to P7 Outputs?

Lots of Questions: What really, are the 'Outputs'; the motor Outputs, the BOB Outputs P2 to P7?
What is actually tested; the Mach3 software's ability to conduct this particular diagnostic process or does this diagnostic actually test all outputs?

Should I leave all outputs in an 'On' state? i.e. P1Q1, P2Q1 etc?

All NC limit switches (L/S) working, M1=X, M2=Y and M3=Z. They registered in Mach3 Diagnostics with the LEDs continuously lit. The LEDs would switch off only when a L/S was activated, i.e. circuit opened. And then all at once that reversed. Now the LEDs light up only if the L/S is activated .i e. circuit opened. Is this normal or did some current reversal take place in the BOB?

Should the Mach3 'Diagnostics' 'Output 1' LED light up. How could I test normal output signals.

Still waiting on motor cables; has been sent I'm told.

What could result from such a reversal, real time direction contrary to coded direction?

Really enjoying the rain after some 6 years of drought and fire but must first find the leak to fix the leak. It's a very slow drip that follows the rafters from somewhere.
A white Christmas this year?

Yes, all boxes ticked for common anode under 'Motor Outputs'

Jog signals functional by hot keys and onscreen jog device. Have not yet tried MDI but will.

My shed's power has shorted after 3 days of constant rain finding its way through a leak in the shed's tin roof and into the wiring. So no electricity being used there at the moment and the project is at standstill for as long as it takes to safely turn the power on again. Then fix the leak.
