@fcwilt the new z-value is 3.025

That sounds very reasonable.

@fcwilt good so far

@icy_snake

I've got some chores to do so I will have to leave for a while.

I will check back later.

@fcwilt ok thx again, i will wait.

The folks at modix don't seem to know what they are doing.

I think it's a case of Modix not having updated their configs for RRF3 yet.

Maybe so but some of the config file had v3 syntax. I didn't get the impression @ICY_SNAKE did it - but perhaps.

@fcwilt Good morning Frederick,

please can we finish today our files. Let me know when you had breakfast.

Wish you a good day.

@icy_snake

Hi,

I'm just about to make breakfast. Give me 30 minutes or so.

Have you had a chance to verify that all is working with:

homeall.g
homex.g
homey.g
homez.g
bed.g
mesh.g

@fcwilt hello frederick,

no problem, take your time.

ICY_SNAKE

@icy_snake All files are fine, i tested them single command.

fcwilt

@icy_snake

Well if those files are all working you are almost done.

What do you want to work on today?

Frederick

ICY_SNAKE

@fcwilt the config_probe.g

which has only the following lines:

; config_probe.g
; config the probe and call the other files.g
;

M950 S0 C"duex.pwm5"
M558 P9 C"zprobe.in" H5 F120 T6000 A5 R0.7
G31 P500 X-18 Y24 Z3.025 ; z value is offset

or i am wrong??

ICY_SNAKE

@icy_snake also a macro to setup the z?

That is all you need. As mentioned by calling that file with M98 in bed.g, mesh.g, etc. you are sure the probe is configured with the most recent values. No need to reboot or restart to get config.g processed.

I was under the impression you had determined a good value for the Z parameter in G31.

As mentioned normal that value is "set and forget" unless your hardware changes.

I suppose I could code a macro to determine that value but as you know it is going to involve setting the physical Z position to some known value to serve as a reference.

Would you like to have such a macro?

Frederick

@fcwilt yes lets do a macro. so whenever i change my bed from glass to aluminium i can run a new setup

Is there are reason to think the correct value for each would be different every time you changed the bed material?

@fcwilt said in Correction of heightmap is not really working:

o think the correc

yes, because the thickness of the buildplates are different.

also another question do i need the

G31 P500 x-18 y24 Z3.005

in the config.g and also in the config_probe.g??

fcwilt

@icy_snake said in Correction of heightmap is not really working:

yes, because the thickness of the buildplates are different.

I understand that but if the correct value for G31 is always the same for each buildplate you could just have a macro which sets the new value as opposed to determining the value each time.

G31 P500 x-18 y24 Z3.005

in the config.g and also in the config_probe.g??

What you should do is remove all three of the probe configuration commands from config.g and replace them with the M98 P"probe_config.g" command. That way the probe will be configured after a reboot or restart. Not essential but it insures the probe is ready to go if you were to issue a command like G30 from the DWC.

@fcwilt ok

so i need only one macro to set the z, correct?
