Correction of heightmap is not really working

[ICY_SNAKE]

@fcwilt
I have no idea for what they are using M280, because i have no servo to set any position.

Not sure why they change the current for the stepping motors.

I believe they copied many codes together to get it running

@icy_snake
@fcwilt ok understand

so we have the bed.g and the mesh.g

now we need to finish the config_probe.g to call the others?

I have the following questions.

How will i get the z-offset value in the g31 command?

do we also generate a z_offset.g?

thx
Dieter

@icy_snake
Frederick are you there??

@icy_snake

I made a mistake on the mesh.g file and have edited it to include the call to config_probe.g.

The bed.g file already had it.

Since the Z parameter for G31 is pretty much "set and forget" I don't use any sort of macro to set it.

I do have a macro to set the Z=0 Datum at the center of the bed - which consists of the G1 command to move to the center of the bed and the G30 command to probe and set the Z=0 datum.

At that point you can verify that the Z=0 Datum was set correctly by using the DWC "jog" buttons to move to Z=0.

If you end up touching the bed before reaching Z=0 then the Z parameter in the G31 is too large by the value displayed for Z.

If you reach Z=0 and are not just touching the bed then the Z parameter in the G31 is too small by the size of the gap between the nozzle tip and the bed.

Once I have determined the value needed, I edit the config_probe.g file and run the Z=0 Datum macro again to be sure all is good.

I also forgot to mention that you should include an M98 P"probe_config.g" command in the config.g file just so the probe is configure after a reboot or reset.

M98 P"probe_config.g"

ok i added it. not problem

[ICY_SNAKE]

@fcwilt the new z-value is 3.025

@fcwilt the new z-value is 3.025

That sounds very reasonable.

[ICY_SNAKE]

@fcwilt good so far

[fcwilt]

@icy_snake

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

I will check back later.

[ICY_SNAKE]

@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.

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

Frederick

[ICY_SNAKE]

@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?
