i made the holes with cambam and it did what it did. i would much prefer a single arc but i thought they had to be less than 180 degrees or some other limit. i just trusted what canbam made. i like

I will try to do it this way. I wanted to use cutter comp but could not figure out how to do it with I J specs. It sort of seemed impossible. Will Mill Wizard make simple easy to understand gcode for

If your willing to do 180 or less you can do R style arcs. I find that most people have a hard time with the I J vectors to tell where the start point is. But the radius seems to be something that

Have you got CAD in any form? Can it export a DXF file? If you have answered yes to both of these it may be worth using a simple DXF to Gcode CAM program to create your Gcode. The one I use is

that is the first place i looked. i did a couple of tests but not a successful one yet. the one in the thumb drive that i have not tested yet should work. i probably got some addition wrong in the

Take a look at this web page, very clear: https://www.cnccookbook.com/cnc-g-code-arc-circle-g02-g03/ :) :)

To answer my own question maybe. It looks like I am j are relatibe so they should not be offset Feb 12, 2022 4:02:44 PM spencer@...:

I have some gcode that I wrote a long time ago, using cambam, I think. It made the circles for me so I did not need to understand G code arcs. Over the years I have move the circular pockets relative

DazTheGas Did a video a while back on setting up the homing and limits don't know if that would help but wouldn't hurt? to have a look

No three switches

Hi Terry Thanks for reply. I have tried using 1 limit and allocating it to both Home and Limit. Problem is when Running G28 the limit trips and stops the Homing functioning, Logical I know!!! So far

I think if you are using one switch for home and the same switch for limit and you are using a smoothstepper. then in the smoothstepper config under inputs if homing motor0 and say using motor0 limit

Hi Terry, N attacments? Question is are you using the same switch for home and limit ? Regards Graham

I have tried every speed and feed combination and almost anything works for 90% or more. It is just that less than 1% where I have to reduce the feed to about 40% and it still chatters. I tried to

I am using three limits here is the pins

Spencer, you might try reducing your spindle rpm. Hardwoods sometimes burn and form a carbon layer at higher speeds.

Hi I have a 3 axis mill developed from a conventional Milldrill with ballscrews and drives added. All working and functioning correctly. As is the home and -ve axis limits. How can I use the home

the motor is more than adequate, i think it is 2 HP wired with a fairly short proper cable. I should check the connections could have loosened. I have a big button estop that cuts power to everything

I'd guess it's a spindle issue, unless you are making really deep cuts at high speeds. Other than cutting through a know, no sharp 1/4" tool should have trouble cutting through any wood. How powerful

I have been having occasional strange behavior making small parts on my cnc router and think I finally figured out what is causing it. I thought it was miss-feeds or just about anything else but have
