I noticed that changing the $3= settings in the console does not make any changes. unlike Lightburn, is a restart required or does this just not work yet?
These settings are firmware settings. MillMage or LB are just senders. If it doesn’t work, either MillMage has an issue sending the commands or the machine does not react to it well. If you send it, do you get an “OK” message back?
Yes, I do get an ok. I have used this method of changing settings before. Only Not working in Millmage’.
So I checked and the $100, and $101 is adjusting and working properly. Seems that $102 is not responding. I have changed input settings from $102=360 up to $102=460 and no setting changes are made
You have a Z calibration issue?
The $100-$102 settings (=800) on my CNC are all the same. This suggests all 3 have identical stepper motors and lead screws. Is your machine a moving gantry type or custom built?
Did you try entering $102=360 in the Console window instead?
Hello, It is a 3018 that I have extended. X axis moves on gantry, Y axis moves on bed. I am entering the $102=, into the consol
Seems you have another issue. If you get the OK command back from the laser, it was working as expected. Be aware that MillMage and LightBurn are only transferring data, they are not doing anything. There is nearly no chance that this bug is related to MillMage. What is your communication port configuration?

This is the only reason you would change the $102 parameter.
Looked at your file some more… According to your Setup, your workpiece would be full size on a 1200mm x 4800mm (48”x96”) machine. Your part is about 1200mmx460mm, so it is 4” wide? You say it is an extended 3018, but I seriously doubt you could extend that machine that much.
I do not believe it is intentional, but your answers are not giving us the information we need to help you. I also believe your Setup may be contributing to your issues.
If you are really using a 3018 controller to manage a 4’x8’ machine, please let us know.

@MikeyH I am confused to what file you are refering to? No where have I mentioned the size of my work piece or size of machine. I did say it is an extended 3018, that I did myself. my work area that the spindle tool makes measures 570mm on the X axis and 380mm on the Y axis. these are measured by marking with the spindle on the spoil board. since it was a learning extperience I do have some flex movement on the X axis guide rods resulting in the need to slow down while engraving in wood so that spinle does not lift out of work piece
I am using the stock stepper motors from the 3018. I did find that if I engrave a 200mm line with the X axis and the Y axis seperately using only the jog command the result was a longer line than 200mm. This is why a calibration was nessasary. Using the $100=, and $101= I have the axis caligrated to within 0.10mm. For the Z axis I zero`d the bit to the work piece, set the jog commant to move 30mm upward. I then measured the distance from work piece the the bit. I made adjustments with the $102= command. The Z axis is not calibrated to within 0.01mm of the jog command.
My apology! What we have here is an ID10T error on my part. I apparently was looking at a Lightburn file I had downloaded from another posting. I knew switching to decaf was a mistake!

No Worries, I try to follow along and make sence of things as this is a learning adventure for my. I hope I have explained everything well enough for others to follow along. Also If I am doing things wrong or do not make sence, or there is a better/ easier way to do it, I hope others will correct me. I have other problems I am scratching my head about also
