So I have had to setup the extruder to axis B.

When I read the outputed gcode from slic3r in notepad it is controlling axis x,y,and z and is using axis E for the extruder axis.
I was hoping that there was a way to change setting in slic3r so it outputs the extruder gcode as axis B and not E.

Hope this makes sence new to 3d printing.

An example of what I am talking about, is there a way to change the E output to B in Slic3r , I could see if I can change the axis in mach 3 to E then that would solve the problem but dont know if this is possible.

I modified dimension.py per this post that removes the resetting of the A axis. It works great. No pausing.

I can see the point of visualization for CNC machines, you don't really want to stick your head near to a live CNC, and anyway the workpiece may be obscured by coolant. If I want to see what my printer is doing... I look at the printer. I don't need an on screen display for my laser printer, why do I need one for my 3D printer?

So I can see this is a method to introduce 3D printing into the existing hobby CNC area, but it is never going to persuade existing Reprappers to start using CNC type kit for 3D printing.

If there are any real benefits from CNC techniques, such as 3D tool paths, these can easily be adopted.]]> bobc Mach3 Tue, 14 Jan 2014 02:16:28 -0500 https://reprap.org/forum/read.php?264,109057,109057#msg-109057 https://reprap.org/forum/read.php?264,109057,109057#msg-109057 SeeMeCNC crew. I have asked that this Mach3 3 forum be added so that we all can share how we are using Mach3 to control our 3D printers.

I look forward to contributing all of the information we have found to use mach3 with our H-1 printer kits, as well as learning others tricks.

Thanks,
