6. I think someone is planning to install one of my mini IR sensor boards to use instead of the bed switches. That would allow the use of stronger springs, or no springs at all.

What is the price and availability of your mini IR sensor boards. I am presuming these are compatable with Build Tak

Thanks fo sharing.
1. It sounds like you have your slicer configured to generate absolute extrusion coordinates. Use relative extruder coordinates instead. If that's too difficult, add a G91 command at the start of sys/pause.g and sys/resume.g.
2. Edit the sys/homedelta.g file on the SD card and remove the G1 movement command at the end.
3. The Fisher extrudsr is direct drive so the motor current has to be set quite high. Using a geared extruder would allow you to use a lower motor current.
4. I think any printer that mounts the electronics horizontally and in a confined space should probably use an electronics cooling fan. Although if you use a geared extruder and reduce the extruder motor current, then the Duet will generate less heat.
5, 7 I can't really comment on as I don't have a Fisher.

The problem is that the Fisher nozzle is about 17-18mm below the effector so not enough clearance for the IR board underneath.

7) Wiring on the back panel needs to be shifted else the carriage will hit on it.

Regarding point 1, can anyone explain why the E coordinate should be relative while all the others are absolute?

As I said, that does not work. M83 does as expected, but M82 then resets the E value to zero. M120 + M83 followed by a M121 at the end of the file does work.
