Config for Mach3

Recommended Posts

I'm printing with Mach3. I manually control my hot-end, heated bed, and fans. I need a way to remove all M codes, and change the extruder from E to A. With Skeinforge I am able to do this with replace.csv. Can I link to a replace.csv by altering current_profile.ini, or do i need to place what I need for a replace.csv into the .ini file? Would also like to remove comment lines in gcode.

No problems running manually edited code.

I see there is a Z-lift plugin, is there a jitter plugin to randomize the perimeter start points? Copied over jitter.py for Skeinforge but doesn't display in plugins.

The plugins do all their editing after the gcode is created. So if you think about what a jitter plugin would have to do - I think it's easier to write an entire slicer. In other words it's too hard. I think.

What you ask for would be very appropriate for a plugin (change E to A, remove M codes and comments).

The E to A is the easiest part - you can also do this in most editors. Most editors such as notepad (better to use a really good one like notepad++) can do "replace all" with a search string and replacement string.

The tricky part would be getting rid of all the comments and m codes. Not sure how to do that.

From originally starting printing with Skeinforge, replace.csv easily replaces E with A, and will also remove M codes. There is a replace.csv= place holder in current_profile.ini. I am easily generating 100-200mb gcode files with a 0.25mm nozzle and 0.1mm layers. looking how to properly use the replace.csv in current_profile.ini.

I need to replace E with A, and can work with changing M to ;M, and T to ;T

Skeinforge replace.csv format is



but I can't figure out how to format it in current_profile.ini.

Is there anybody that has done the post plugin for mach3?

It seems to be quite ok if I remove line from the beginning and the end and replace E to A and M to ;.

Only problem is how to get A to B after T1 if using dual extruder.

If someone can inform me how to use the replace.csv in the current_profile.ini file, all you would have to do for dual extruders is to first change A to B, then E to A, very simple. You just process the second extruder before the main extruder.

Upon further investigation, it looks like replace.csv is no longer a working feature as I loaded up version 12 of Cura and the replace.csv works as it should.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
