Finally my Delta is up and running. After following the delta calibration procedure it was time to run a mesh compensation. Probe radius 200 and spacing 20. I think I can be happy with the result.
Number of points: 305
Probe area: 1296.0 cm²
Maximum deviations: -0.049 / 0.051 mm
Mean error: -0.003 mm
RMS error: 0.016 mm
Bed: 8mm cast aluminum, diameter 510mm
Build height: 925mm
Smart effector
Going to use 80mm rod spacing. Design and manufactured an adapter for the smart effector. CNC milled aluminum, weight 38grams. The plan is to use an Orbiter 2.0 extruder.
Made some mounts for the Orbiter 2.0. Works great with my 80mm smart effector adapter. Weight is 12 grams.
Found this on YouTube, maybe already discussed but I think it could help.
My current ongoing project is a large delta printer. Bed size is 510mm and the total height will be 1800mm. The goal is to have a very rigid design so I went with V-slot C-beam 40x80 for the towers and V-slot 20x80 between them. I could not find any suitable corners so I made my own design in Fusion 360 and my oldest son helped me to fabricate them with a CNC-milling machine at his work.
I have all the extrusions and all corners but so far nothing is assembled yet but I have some renderings and a photo.

Without having the 0V connected to ground/earth and the frame of the printer connected to earth/ground, then for example the fuse for the bed heater may not trip if you get a short to the frame in the heater.
I always have the 0V connected to ground/earth and if there should be any problem with ground loop I use the laptop running on battery only. Just my opinion.

@captain_sq check here what you need to convert. You can also make a new configuration with the config tool and then compare it with the old one.

I can confirm that this is now fixed in 3.4-b7. Thanks @dc42
@Fred-Y I have been thinking of that solution for my Orbiter 2.0. With my 80mm rod spacing adapter the Orbiter can be mounted horizontally.
Maybe an output of M122 after this strange jogging could give some information?
Nice Project! Good idea to involve your son, that is what I'm also doing. We are planning to build a larger delta and our goal is to think outside the box and design everything in 3D and also manufacture parts by ourself and not use any printed parts. We are not trying to build the cheapest printer. Accuracy and rigidity is priority.
@edchamberlain are you thinking of a Tricept robot style printer?
I have read the Wiki about how to choose type of stepper motor for my Delta printer but I'm not sure what way to go. My plan is to design a larger Delta (1500mm high), I know that the size of the printer doesn't matter so much when choosing motors but the guide carriages will be made of metal instead of plastic so a little bit heavier than ordinary. Printing speed maybe up to 200mm/s.
My hardware is Duet 2 Wifi and 24v supply. I also want to use 0.9 degree motors.
I have been looking at these two:
17HM192004S
Motor Type: Bipolar Stepper
Step Angle: 0.9 deg
Holding Torque: 46Ncm(65.1oz.in)
Rated Current/phase: 2.0A
Voltage: 2.8V
Phase Resistance: 1.4ohms
Inductance: 3.0mH ± 20%(1KHz)
23HM22-2804S
Manufacturer Part Number: 23HM22-2804S
Motor Type: Bipolar Stepper
Step Angle: 0.9 deg
Holding Torque: 1.26Nm(178.4oz.in)
Rated Current/phase: 2.8A
Voltage: 2.5V
Phase Resistance: 0.9ohms
Inductance: 4.5mH ± 20%(1KHz)
Please give me some advise.
Thanks
Fredrik
Thanks everyone. I just ordered a set of 5 42BYGHM810. It was cheaper to buy a set instead of 1x3.
The plan was to have the belt going between the wheels inside the C-Beam but with pulley with 20 teeth there is no room. Is there any disadvantage to have the belt connected off center and having the free side of the belt between the wheels (picture 1)?
Another solution is to have the motor, belt and pulleys rotated 90 degrees (picture 2 and 3).

@jay_s_uk thanks for reporting that - I will flag it up
Another thing in the section setting up network:

Shouldn't the subnet mask be 255.255.255.0 instead of 225.225.225.0?
@luka_dam You are welcome. Please mark this topic as "Solved".
@luka_dam made a quick check in the manual and it looks like positioning mode type 6 supports TTL levels.
