Cutting feed rate defaults to 80 IPM <resolved>

Post by lnindustrial »

Started making my first cuts and I noticed that no matter what profile I choose in the profile manager the cutting speed is 80 IPM. I am using sheet cam for the post processor but I have ran the "hook" program that came with the centroid software and have the same issue. I do not have the THC board so is that the issue? If I placen a F value in the G1 etc. values then it will feed at the F value for that block and then return to 80 IPM. Is there something I am missing or do I need the THC board in order for the feed valule stated in the profile manager to be reflected when running the program? My setup will run easily 300 IPM wiht the rapids.

Sounds like the profile you have selected has a feedrate of 80ipm. A commanded feedrate in the gcode will last until the next M61 pierce macro when the profiles settings are re called.

I thought the same thing however there is no command feedrate in the code. It doesnt matter what I run, including the hook program that came with the centroid software, they all cut at 80IPM. If I do put a feedrate in the G1, G2 or G3 then it will cut at the speed I specify however the next M61 with the pierce cycle it will revert to 80IPM.

With the Acorn plasma software there will never be a feedrate in the g code. The feedrate is defined in the Profile Manager for the material you are cutting. This is what the M65 does in the beginning of the g code. You have to tell the software what material you are cutting and at what amperage BEFORE you start the cut. Once you define the material this sets the feedrate, target voltage, pierce settings and cut height. It's not in the g code, if it is your PP is screwed up.

This is the beauty of the Acorn software, you have one g code file for all thicknesses of any material.

All this is in the plasma manual, please take a moment and read it thoroughly.

I have read the manual thats why I'm coming here for help, I load the material in the prifile manager prior to the cut, in fact I have tried to load the profile and then load the g code then cut, load the g code, open progfiel manager and load the material, then cut, with each time having the same result of only 80IPM.

Can you post a fresh report from the machine please. Almost sounds like the MAX rate in the wizard axis Config menu is set to 80ipm.

Once the report is posted I can run that on my Acorn and see if I can find what's going on.

Anytime when you edit a 'stock' Centroid macro, it is a good idea to save a copy of the original to compare or go back to when something goes wrong.

Also if you ask for help, please call out any macros that may have been changed that will make it easier for us to help you. :D

I corrected your custom M61 Macro to get you back to normal and attached it.

The Macro I've attached is still skipping the touch off cycle and I only removed the F80 and added the <FEEDRATE>.

I've Copied your M61 macro here to show where the issue was. To Use this fixed M61macro download the file I've attached and just drop the file into your cncm folder.
