Hi folks, having some trouble and need some advise.

Just got my small 20x26 router up and running, and I'm having trouble with Mach3.

Everything worked fine with LMC2, so I'm pretty sure wiring is correct.

Issues -
1. When Jogging X and Y, axis moves in same direction when pressing +/-
2. Z axis doesn't move at all
3. Motors are screaming at me

About the drivers and build -

XYdrive XD14 bob
XYdrive XD8 drivers

Step Time - Min. 1u
Step Space - Min. 1u
Direction Hold - Min. 200us
Direction Setup - Min. 200us

Motors -
Vexta Nema 23 PK266-02A
2 Phase 1.8 /step

PSU 24v switching 12.6 amp

Acme thread 1/10 single start

Any assistance is appreciated!

Hi Yesd0g,

I think you need to check your pin assignments for step and direction (ports and pins) also reduce your Velocity and Acceleration settings (motor tuning).
Do you have the recommended settings in your machine manual ??

Thanks Tweakie.

The machine is a home build, so no recommended settings other than the attached screen shots.  I'm pretty sure the pin assignments are right...

Here's a video of the axis running with LMC2.

Somewhat hard to decipher, but I believe this is the part of the XML where the motor assignments are.

<Motor0Active>1</Motor0Active>
  <Motor0DirNeg>0</Motor0DirNeg>
  <Motor0DirPort>1</Motor0DirPort>
  <Motor0DirPin>2</Motor0DirPin>
  <Motor0StepNeg>0</Motor0StepNeg>
  <Motor0StepPort>1</Motor0StepPort>
  <Motor0StepPin>1</Motor0StepPin>
  <Motor1Active>1</Motor1Active>
  <Motor1DirNeg>0</Motor1DirNeg>
  <Motor1DirPort>1</Motor1DirPort>
  <Motor1DirPin>4</Motor1DirPin>
  <Motor1StepNeg>0</Motor1StepNeg>
  <Motor1StepPort>1</Motor1StepPort>
  <Motor1StepPin>3</Motor1StepPin>
  <Motor2Active>1</Motor2Active>
  <Motor2DirNeg>0</Motor2DirNeg>
  <Motor2DirPort>1</Motor2DirPort>
  <Motor2DirPin>6</Motor2DirPin>
  <Motor2StepNeg>0</Motor2StepNeg>
  <Motor2StepPort>1</Motor2StepPort>
  <Motor2StepPin>5</Motor2StepPin>

So on the bob, the corresponding pins assignments are:

All on comms port 1

x-step  1
x-dir    2

y-step  3
y-dir    4

z-step  5
z-dir    6

x-enable 14
y-enable 16
z-enable 17

Hi Yesd0g,

OK, from your information it looks like your ports and pins are configured correctly (it is just unusual to use pin1 for motor control).

Now I would try - in Ports and Pins select Sherline 1/2 pulse mode, restart and see if this makes any difference. Also make sure Kernel Speed is set to 25000Hz.

Hope this helps.

Friends, hi.
I'm from Brazil and I'd like to know were can I buy the boards :
- XYdrive XD14 bob
- XYdrive XD8 drivers
Does anybody can help me?
Thanks a lot.

Hi Wagner,

Xydrive Automation LLC are probably not the best business to try and buy from - there are much better devices available, with better support etc. Perhaps look at the CNC4PC site  http://www.cnc4pc.com/Store/osc/index.php  or the Gecko site http://www.geckodrive.com/products-order.html - both have a much better track record.

Hi Tweakie.
Thank you, but I have to do a maintanance in a machine that have some drivers from XYDrive, and I never had any problems with them, and here in Brazil it's dificult to buy them, can you help me, where do I can buy it in any shop that send them to Brazil?
