I am curious as to why if I change the settings on the microstep drivers it makes no difference to the amount of movement?

I think you have a problem there somewhere - changing the driver's microstep settings should make a difference to the distance the machine axis travels but you may be seeing some compatibility issues with that breakout board.

I wrote to the factory, but they are Chinese without technical support.
Just a salesperson who's trying to help me.

I have every sympathy but that is exactly the reason that many of us do not buy the cheap products. It is often better to pay a bit more for a product (perhaps still made in China just the same)  BUT which includes good technical backup services from the supplier.

Hi Rocky,

Direct drive belt systems usually have a small number of steps per unit - that is just the way it is.

Please excuse me for not understanding but if your machine is working OK then what is the problem that you are having ??

Hi Vince,

You will need to do a number of modifications to the code (including feeds and speeds, possible multipass and setting a depth for the engraving toolpath) because I just didn't have enough information to do it right first time. 

Out of curiosity what is it to be used for ??  (fingerboard radius gauge perhaps ?)

I think the only foolproof method is a mechanical endstop possibly tripping a switch which disables the axis drive.

(When using my vacuum table I use an adjustable (preset) mechanical stop but I have my Z axis drive current set such that no harm will come to the machine if the endstop is accidentally hit).

There has been a lot of discussion over the years regarding Kinematics and that Mach3 does not support this type of control.
To a certain extent this thread applies http://www.machsupport.com/forum/index.php/topic,29706.0.html

I don't know if it ever came to anything, perhaps you could contact the author via his website ?

I would be most interested in following your progress.

I haven't tried it or anything but see if this is any good.

Hi Vince,

What diameter cutter (or kerf width) are you planning on using when cutting these parts ??

Further clues ? ............... when I go into config I can access all the sub tabs except motor tuning.  Just nothing appears on the screen when i try to access it.

Sounds like you do not have the parallel port driver installed. This can be installed by running the DriverTest.exe (Mach folder).

Hi Skipper,

Setting a different Profile within Mach3 for each machine takes care of the various settings differences etc.  It is then just a matter of swapping the Parallel Port / USB or Ethernet cable from the PC depending on which machine is to be used.
There are those who use the same motor drive controller but, in my case, I prefer separate controllers for each machine (saves swapping too many cables).
