Hi Burf86,

You nearly fooled me there - in your initial post you said the board was a JP328C but from you pic. I see it is a JP3163B 

I have attached a modified .xml file which I would like you to try. Change the name of this .xml to the same name as your existing <your profile>.xml and then copy it to your Mach3 folder overwriting the existing .xml.
 
Please check that your JP3163B board has all the switches set…

K1 – ON
K2 – ON
K3 – OFF
K4 – ON

This is the setting for 1/8th Micro stepping.

SW1 – ON
SW2 – OFF
SW3 – ON

This is the setting for 2 Amp stepper motor current.

Perhaps let me know how (or if) it works and we can go on from there.

Hey Tweakie, thanks for taking the time on this. Really appreciate it.

I'm not getting any movement at all. The ports and pins weren't selected and even after that still nothing. The DRO says its moving, but no movement on the router.

Hi Burf86,

Something went wrong & I think you are using a different profile and picking up the wrong .xml file but I have removed my .xml download while I check it.

No worries though we can take a different approach…

Make the following changes to your Mach3 settings and save the changes at each stage.

In Config. / Motor Tuning…

Set each axis and save after each change to…

X and Y Axis…
Steps per  400
Velocity  2000
Acceleration  200
Step pulse  5
Dir Pulse  5

Z Axis…
Steps per  400
Velocity  1000
Acceleration 100

The attached .zip file has screen shots of the other config. changes.

There will be some more changes but this should do to start with.

Tweakie.

Still no movement I'm afraid. I took a screen shot of the Mah3 folder, maybe I didn't delete something I was meant to when uploading that profile you sent?

Going to re-install and then input the setup you screen shot for me.

It moves now, but the calibration is so far out. Tell it to move 50mm and it travels the whole length of the bed and hits the stop...

Sounds like progress 

Initially check that you have Mach3 set in mm Units (Config. / Select Native units).

Now you need to check the leadscrew pitch of your Z axis – I am assuming it is 4mm (one complete revolution of the lead screw moves the axis 4mm).
Steps per unit are calculated as follows…
Your steppers have 200 whole steps per revolution & at 1/8th microstepping that makes it 1600 steps per revolution ( 200*8 ). If your Z axis moves 4mm in one complete revolution of the leadscrew then to move it 1mm or 1 unit would require 400 steps (1600/4). This would make the steps per unit 400 in Motor Tuning.
You should repeat this measurement and calculation for the X and Y axis just to check that they are to be set at 400 steps per unit.

Next is axis direction…
Standing at the front of the machine, if you press the up arrow key on the keyboard the gantry should move away from you. If it moves in the wrong direction then change the Direction Low Active state for the Y axis in Config. / Ports & Pins / Motor Outputs and apply the change.
If you now press the left arrow key the carriage should move to the left. If it moves in the wrong direction then change the Direction Low Active state for the X axis in and apply the change.
If you press the Page Up key the Z axis should move upwards. If it moves in the wrong direction then change the Direction Low Active state for the Z axis in and apply the change.

One step at a time, we will get there 

Tweakie.

One step at a time, wahey! 

Things are starting to come right! The lead screw pitch is indeed 4mm and my motor tuning is now set to;
X-397.186 - 800 - 200 - 5 - 5
Y- 397.4377 - 800 - 200
Z- 399.002 - 200 - 100

Attached are a couple of pictures. One is showing how it cut before we fixed things, and the other shows what it's doing now. Much, much better, but could still do with some fine-tuning I think

Excellent result.

Now the learning begins 

Tweakie.

So you'd say I'm good to go and start playing?
I'd appreciate any pointers to stuff I need to learn!
