so after several days of trying to get good results i have decided to unmount the IR Probe. It make no sense with my FR4 Plate.

does Anyone have ga good magnetic plate which will work with the IR sensor??
Bed temp could be 90 degree max

Thank you

@fcwilt

Yes but it’s a good Surface to print.

Could it help to decrease the probing points?

Or could it help to do a sanding of it?

@fcwilt

Ok, I also have a casted aluminium plate which is on both sides milled. I think my FR4 plate is the reason why it is so different. It’s a bit translucent.

Tomorrow I will give a try with the mesh.

@fcwilt
ok i had done the neeed config and have leveled it. after several leveling, best i could do was about 0,03mm to adjust.

then i had done a G29 and heres the height map:

Any idears?

@fcwilt

Ok, machine is now running as aspected (but without mesh compensation)

I also have designed a new holder for the probe.

So and what are the best steps for next?

@fcwilt

after pid tuning i have decided to add "R4700 behind the M308.

Now bed has heated really fast. Is there something agains R4700? I had this thing in my old config.

Now it looks like:

M308 S0 P"bedtemp" Y"thermistor" T100000 B4400 R4700
M308 S1 P"e0temp" Y"thermistor" T100000 B4400 R4700

@blacksheep99

no, i have put the M307 in config directly..

; Heaters

M143 H1 S280                                   ; set temperature limit for heater 1 to 280C

if i put it in override, what have i to put in?
and in config should only M501?

@blacksheep99

yes i have one done for the heater and the bed.

Bed:
Warning: heater behaviour was not consistent during tuning
Auto tuning heater 0 completed after 4 idle and 25 tuning cycles in 5317 seconds. This heater needs the following M307 command:
M307 H0 B0 R0.957 C113.0 D6.66 S1.00 V24.2
Edit the M307 H0 command in config.g to match this. Omit the V parameter if the heater is not powered from VIN.

Heater:

M307 H1 B0 R2.746 C97.9:59.2 D5.41 S1.00 V24.2

one question:
after firmwareupdate now it takes very long to heat up the bed. is this normal?

@fcwilt

hi Frederick

this is the message i got:

Error: Heater 0 fault: temperature rising much more slowly than the expected 1.3°C/sec
Resume state saved
Warning: Tool 0 was not driven because its heater temperatures were not high enough or it has a heater fault

@fcwilt

so this is the new config. I hava adjusted all i see to fit with the old config

@phaedrux

ufff spent the 4 last hours to upgrade to 3.3. holy sh... nothing was working anymore. had to switchover to bossa.

Now it works ok. but i get a heater fault. i will try to compare to my old config

@fcwilt

okay thank you for this information.
I think i can update this weekend. but i'm not shure if it works, because i have tried it befor i have set up the machine abd i always got errors. If i update to 3.3, can i use the old config or should i do all new?
(because i'm not so good writing these files)

Yes i can confirm that my coordinate system is right handed. as you described.

Hello again,
so print is done and looks good, bed sems to be flat!

but why is this heightmap looking like this? It was made directly after the print. I'm very confused

@fcwilt

Hi Frederick,
maybe it have discribed it wrong in the title. I would like to get the Z height with my IR Probe and then compensate any hills and deeps getting the mesh...

I have 4 adjusting screws, and have now leveled on the fly. Looks good now. Mesh is deactivated.

If after this print i will send a G29 then heightmap should be really flat.. Or what do you think?

Okay guys I have rewired my printhead and put the hdmi cable out, maybe it is more flexible now. I think I will give it a try

@gip_86

@droftarts

Hi Ian, yes you‘re right. It hangs in front of it, because first it was not planned to mount a probe. Please see the pictures below.

Edit: first have to check how to upload pictures by iPhone…

Hello everyone, i'm new to this forum because i have read a lots of hours about mesh compensation and auto Z leveling. but i can't get it to work the right way.

First i would like to introduce my machine:
It's a Hypercube evolution (CoreXY) and i have spent a lot of time to build it up very precise.
As printplate i am usung a FR4 plate which works very well on my other printer. Electronics is a duet 2 wifi. Firmware is about 2.xxx (for now not able to update it to firmware 3.xxx)

Ok, but now lets go over to my Problem:

In the past i have leveled the bed with a piece of paper ( Hot nozzle and hot Bed) and i've got the following result:

So then i decided to buy a IR Probe height and use auto probing with mesh compensation. I had read all de topics and manuals multiple but still not got it to work as suspected. The IR Probe is not the original one, but i think it works very well.

What i have done:
I had checked several times with G30 what my IR is doing, it is consent and will only change the trigger height about 2 Microns.

Then i had sent the following commands:
G30 ( in the middle of the bed)
G28
G30
G29

After finishing G29 i got the following result:

I don't why know but lets go to next step:

mesh grid is loading, for the print, Z Axis does compensating but not enought, or wrong. And first layer shows what i see if i do printing with manual leveling. (Left corner in back area is to high and material is not coming out)

Please see also my Config / Bed / HomeZ and HomeAll.

would be great someone could assist me....
