PlasmaC questions new setup

Yes and saved but not there anynore.

Try it once again

Now it works BUT.........

It teared my stepperholder in pieces as it is moving way too high so something must be wrong in the settings.

Is the safe/probe height wrong? Should it be -40 instead of 40?

Safe Height and Probe Height are relative to the Z minimum limit.

You should set the drive current to something low enough to work, but not destroy something while you are testing things.

Because you have the servo period at 2000000 you also need to change the P settings in the ini file from 1000 to 500

this example is cutting at like -50, pressed pause and the rocket went up and ripped the rest of the stepper holder

This must be wrong
[AXIS_Z]
MIN_LIMIT = -105
MAX_LIMIT = 105



Good reason to 3D print parts as Mr Murphy is always around

I set my Z limits like this. linuxcnc.org/docs/2.8/html/plasma/plasma....html#_initial_setup

I set my Z minimum limit as zero and maximum limit as a positive number.

OK, now printing a new part so test later.

I really appreciate all support for an old fart like me = novice


Then I need to add in INI HOME = 95 as an example right?

Now the Z is in working order again

Question
After homeing Z it moves 15 back over the home switch and sets 0
But I need this to be a positive number like 95 = MAX_LIMIT and show this in DRO. Need the MAX_LIMIT be past home switch so I can reach it when homeing.

Where can this be set??

HOME_USE_INDEX = NO
HOME_OFFSET = 15.00000
HOME_SEARCH_VEL = 10.000000
HOME_LATCH_VEL = 6.00000
HOME_FINAL_VEL = 2.00000
HOME_USE_INDEX = NO
HOME_IGNORE_LIMITS = YES
HOME_SEQUENCE = 0

I can´t wrap my head around this, I follow the the config steps in users guide and I still have the problem with keyboard PgUp the torch is going down and DRO is counting UP positive numbers from Z home is in DRO 0 when it should be high positive number.

Obviously there are settings that are wrong.
