Up and running, MACH4 now has the same scaling capabilities as MACH 3

So from my Interest, the subject is closed. 

Thank you,

Thank you, I would appreciate that.

With all the projects I have in work, there’s no hurry.

Stay safe

Thank you for the reply.

I totally understand having to reacquaint yourself with Modifications you’ve done after A period of time.

Would it be possible for you to send your MACH 4 profile?

Since you have it working on your machine, maybe I could modify your profile to fit my machine?

Thank you,


What would it take for me to have MACH4 Feel like MACH 3

Probably not that much....but why? —————-Craig

Thanks for the response.
 I understand what you’re saying about MACH4 being so much better Then MACH 3

In my shop, I frequently use the X and Y axis percent scale feature within MACH 3 quite often.

I have MACH 3 on three different machines and will be converting 2 of them to MACH4 and would really like to have the same feature for scale on all three machines. 

So I’m really interested in what it would take to make my MACH4 machines do the Axis  scaling like MACH 3.


LAST UPDATE---Figured out the "looping" problem and I can now scale any axis by simply entering the value in to the DRO's and they will scale just like you could do in mach 3. When  I select regen tool path it will resize the picture on the tool path table as well as update the extents.

What would it take for me to have MACH4 Feel like MACH 3 Relative to changing the Axis scale percentage in a box next to the axis DRO

"I’m leaning towards the brand." 

should have read.

"I’m leaning towards the Glowforge brand."

I’ve considered the K40 Chinese machines but would prefer getting something that’s more turnkey

Hi Chuck,

Unfortunately the quality of the mechanics (and the optics) of the K40 is very low (it is manufactured to a price) and they are better avoided if you can.


Hi Tweakie,
I’m hearing similar things on the K40. Plus the software doesn’t sound very good either.

I’m leaning towards the brand.  Their machines seems to get good reviews, they have three models.

you mean you are using an external physical potentiometer??
and if so, what value would that be?  also, I'm guessing it's a LINEAR POT right?

Hi Tweakie,
Yes, it is an external linear potentiometer.

It varies the voltage going into the laser power supply between 0  and 5 V DC.. this sets  Laser Power from 0 to 100%.

On my machine, I tried using your suggestion of using a 74LS00 NAND Gate, but because my laser Tube is fixed vertically on my machine and the heavy xy mill table moves, I elected not to do raster engraving on the this machine that I originally set up for cutting.

I’m looking for a  laser engraving machine more like the one you built for doing Raster engraving.

I do not have a special screen for my laser. I use the same screen that I have for a 4 axis  milling machine.

 Prior to the cut I set the percent laser power using a potentiometer.

Everything else is controlled by the post processed Gcode file.

You could use the M 10 and M 11 to turn your water jet on and off and set the pressure similar to the way I set my laser power.

Fusion 360 has a very good post processor for water jets, Laser and Plasma Cutter‘s. It allows Lead in and lead outs which the subject post processor does not accommodate.

Are you using MACH3 or 4?

Thanks Craig, I was not aware of G51
