Ender 3 Pro with V1 short

I sell four Ender 3 Pro 3D printers that have been used extensively over the past two years. Deputy clerks have gone about 400–500 hours. Today V4.2.2 cards are flashed with Marlin while the writer with v1 has cuts. Not sure how they work with Marlin because I just short them with clippers + mainsail. If you want you can buy with a Raspberry Pi 3 to continue using Klipper.
The system as a whole is working but the thermistors (what I think) have started to fail ihop one after another so it does not just go to press play and run without all should need little maintenance.
Upgrades made:
– The building plates are replaced with 3mm glass chips
– The springs for the building plate are exchanged for silicon dynor.
– Upgraded extruder.
– All V4.2.2 printers have MKS 3D Touch Sensor(Not configured in Marlin)
– Heatbreak that makes the bow not directly against the nozzle (V4.2.2 writers)
and then a little regular entertainment on everyone.

If you are interested in all four you can get a judgment for 2250
