Grab a set of these. Saves a lot of room and they push some air. With my fan and nozzle, it is right at 50mm tall and fits under my effector mounted vertically. Working on a new mount to put both fans on there.
I ordered the set of two. Thanks for the link!
I have a aluminium heat bed painted black and with a 6mm sheet of glass on top of it so it is 100% flat.
just did a mesh grid using the BLTouch and another with the DC42 IR Probe. can anyone help with it?why both of then are giving bad results?

I had this same problem! My print head was visibly stuttering during perimeters where one perimeter pass would end and the next concentric perimeter pass would start. The issue was my jerk speed was too low. For some reason, M566 in the config.g file for jerk or instantaneous speed change is in units of mm/min rather than mm/sec, so you have to be cognizant of that when you dial in your settings. I just stepped mine up to 2400 mm/min (40 mm/sec) and now my perimeters are printing beauteously, and not leaving an obvious bump where the part's seam is.
I really hope this solves your problem. It solved it for me!
I don't know if you'll see this, but THANK YOU! This turned out to be exactly my problem.
If the Duet is quite old, then the most likely cause of the problem is that the PHY chip isn't adequately soldered to the PCB. When this happens, using hot air rework equipment to reflow it sometimes fixes the problem. Otherwise the PHY chip needs to be replaced.
I haven't thought this through properly but one possibility that comes to mind is that the "R" parameter has changed in firmware 1.19 onwards. Do you use "G1 R" in any form in your tool change macros? If so, and if you are using firmware 1.19, you now have to specify which axes the restore points are used on. Dunno - haven't thought it through but if you use "G1 R" in you tool change macros, you may have to play around with the X Y and Z coordinates.
Seems that I'm in the same club. When I extract the number from Dougal1957, the difference is very small
But from the webcam point of view, seen through an 'old' device, I like thinking about reusing old abandoned devices.
Quality is very good. It's only a bit unusual one has to boot a webcam …
Generally, calibration issues with the IR probe come down to two issues:
Effector tilt- You have the probe offset from the nozzle by some distance, however due to the geometric shortcomings of your machine, the effector may be tilting very slightly at different x y positions (ie rods not space properly at both ends etc), because the probe is offset and the effector is tilting, it may be closer to the bed at one xy position than another.
IR interference - reflective surfaces etc. Sounds like this isn't the issue. I'm sure the experienced gang here will help you sort out the gcode/config confusion you're having, but if that doesn't work out, use a spirit/target level on the effector to see if you're dealing with effector tilt. You can use the H parameter in your bed.g to attempt to calibrate out effector tilt, but I've had mixed results doing so personally, best to address why your effector is tilting if that turns out to be what's happening.
On delta and SCARA printers, the only moves allowed before homing are G1 S1 moves (homing moves) and G1 S2 moves (special moves). I have it in mind to extend this restriction to other printer geometries in the next firmware version.
That sounds like a great idea. Im sure there allready is a lof it internal variables that could be interesting to some while debugging. I agreed that it might have to be estimated by layer height after its printed to het it exact but instant value on bigger testpieces wouldnt go that much up/down. Maybe this should be put on the wishlist if its not only me geeking out here ^^
I might be completely wrong but when I started building my CoreXY, I was told that if I tightened the belt(s) too much I would get lines on the parallel side of the axe that require the most resistance…
I am only posting this since it's pretty close to what I am reading.
Thanks for the tip. I could try loosening up the string tension. The principle should be the same as a belt.
The delta radius needs to be calibrated. See https://duet3d.com/wiki/Calibrating_a_delta_printer. With 1.19 firmware and Duet Web Control, you can even run auto calibration without a Z probe, by setting probe type 0 (parameter P0) in the M558 command in config.g.
