I am really new to 3D printing seeking to make adaptive handles for my son with Cerebral Palsy. I started with a Monoprice Delta Mini and now I am trying to get the bigger HC Maker 7 up and running. I have everything assembled and I can run one of the preloaded test prints on the SD card but it is not sticking to the glass. Any pointer on how to trouble shoot this?

What material are you printing in and what are your print settings (temps etc)?

PLA, bed 55, and nozzle 195 degrees. I re-leveled the bed after doing a pre heat to 55 and then successfully printed one of the test prints. Now I am working on dialing in a Profile in Cura the slicer for this printer. When I set up my Monoprice Delta Mini I found start and end gcodes online, but I have not found the same for the HC Maker 7. I may need to search for CR10 settings. Thanks for helping me out. The doing the manual bed leveling with a hot bed was the missing step.

Looks like I am downloading Cura 3.6 next to find the pre setting for the CR10
