Basic Mach3 configuration data

Confused and frustrated

Stepcraft 420 with mach3

I read on here that ideal steps per Unit in motor tuning is 133.333333.

I tested this on a 8cm square profile job. Result: x-axis= 8 cm, but the y-axis=8.7.

I went then to the section settings where there are steps per unit set button to help you test how each axis moves per unit.
x and z are okay, but moving y double than its command.
Mach 3 suggests automatically adjust it and we have the half of steps per unit for the y-axis, so 66.6.

I then tested and found my square with x = 8, y = 4.4

What happens?

Hello,

I have seen that you used to have a *.xml for your stepcraft 3D printing. Can you send it to me too if you stil have it?

Thank you in advance

Here's my Dropbox foder with some usefull basic Mach3 configuration XMLs for various Stepcraft machines. Addionally you find a 3D print XML for a 420. Hope it helps:

Dear Mike,

Can you share your Dropbox folder again
.
Thanks in advance

Hello, would You be so kind to share mach3 profile for 840 stepcraft?
I sent an email to Stoney but still no response.
Thanks in advance.

thanks

Here's the reshare of my Stepcraft Folder:

You will also find the Stoney configuration there. But keep in mind Mach3 is outdated and gets no service any more. I am on Mach4 with my M500 and works perfectly.

Is it same for SC840?

@q_ntt Hi, can you send me the file XML please, to run Stepcraft with mach 3? thank you

That really sounds like the Y-axis is using a different calibration or even the wrong microstep/driver setting rather than a simple Mach3 issue. If Mach3's auto-calibration cuts the value in half but the movement is still off, I'd double-check the controller settings and make sure nothing mechanical is slipping. I recently read https://stape.io/blog/data-loss-and-leakage-prevention about verifying system configurations, and the same step-by-step approach can help track down issues like this.
