Hi! My name is Wolfgang, I am the developer of RepPanel. RepPanel is a user interface for RepRap based 3D printers that features a 3.5" touch screen with a well-designed user interface to control your 3D printer, setup, monitor or stop prints etc. It recently also supports multiple tools. Have a look here: https://reppanel.com There is also a Online-Demo available! I created RepPanel as a litby seeul8er - Controllers
RepPanel is a user interface for Duet based 3D printers. It is a cheaper alternative to the already available PanelDue. It uses the ESP32 and is optimized for 3.5" displays with 320x480 resolution. If you source the hardware yourself it costs around 25€-30€. A big difference to the PanelDue is that the RepPanel does not have to be connected via cable to the printer. You can put it up anywhere iby seeul8er - Duet
Mounting your X rail on some kind of support plate, that is made from the same material (aluminium ?) as the rest of the frame, could also solve the issue. The support plate would then connect the two Y blocks. That way everything expands/retracts at the same rate (except for the rails - in case the frame is alu).by seeul8er - CoreXY Machines
Thanks! You are right! Torsion could contribute a lot. Maybe I should measure the X-Wobble-Amplitude at the very bottom and in the middle of the z-axis. At the top and bottom end it should be stiffer. The current rail is a MGN15. A lot more rigid than those 12mm ones. I'll start improving the design again once some prints have finished. At the moment I am pleased with the print quality. Then Iby seeul8er - CoreXY Machines
I set up a little project page. I'll update it from time to time when I got time and new stuff happened. I always wanted a 3D printer of my own. Since no commercially available machine fulfilled all of my requirements I went designing my own. Goals/Requirements Max. package: 550x490x500 mm Min. print volume: 300x300x300 mm Budged: 1500€ – 2000€ Fast print speeds: >100 mm/s High qualityby seeul8er - CoreXY Machines
