Is it feasible to use gSender to handle sending gcode from a Mac to a Creality Summon D1 3D printer? The file renders nicely but after choosing the USB port, it is still flagged as disconnected
I don’t think that’s going to work as gSender is made to work with grbl or grblHAL and your printer can’t have grbl firmware as grbl lacks some of the gcodes needed for 3D printers. The codes for temperature immediately come to mind as an example.
Your printer runs Marlin for firmware and I would suggest trying Creality Slicer first. It is a descendant of Slic3r which is a good opensource project that has been forked to create Prusa Slicer, Bambu Studio, Orca Slicer and Creality Slicer at least. The Creality version will have support and print profiles specific for your printer.
Creality may use different names for things but a profile is a set of default settings usually named with a layer height and something like Strength, Quality, Speed, Draft etc. I always start with a built in profile suited for my intended purpose and tweak it as needed. You will find that a printer has a ton of settings compared to a LongMill but you don’t need to understand them all to start using your printer.
Also the slicer doesn’t usually send code to a printer the same way gSender does. In the ‘not so old days’ the slicer would create the gcode and it would be put on an SD card and the card put in the printer, then the printer would just read it off the card. Newer printers can get the gcode through your Local Area Network or the Cloud in some cases. There were alternatives like OctoPrint that you could use on a Raspberry Pi for instance but more and more that functionality is being incorporated into the printer itself as well as the slicer.
I hope you like your new printer! It looks cool, I had not seen that model before as I’m not looking for a new printer and don’t want to envy features mine doesn’t have.
I have found all3dp.com to be a good source for learning about 3D printing. They have articles on everything it seems, from basic workflow to advanced settings to things like printing metal and concrete.
