Thanks to help yesterday on this forum, I’ve upgraded the Cura software and firmware to 2.6.64 (Windows 10) and made several satisfactory prints.
I have one small remaining and repeating problem.
The skirt doesn’t start printing (nothing comes out of the nozzle) until the printer has almost completed its first circuit (on a larger print) or the second circuit on a smaller one with two rows of skirt material.
And when it does start, it doesn’t adhere well, and leaves a loose strand which can catch (I try to pull it off before that can happen, so far successfully).
This has happened both when I start a new print without turning the printer off after finishing the previous print, and from a ‘cold’ start where the printer has been powered off before starting.
I’m using the settings for ABS (IC3D) with material from MG Chemicals, which says it has the same temperature range settings - Hot end 230-240C and bed 90-110C.
I’m using the defaults from IC3D: 240C and 105C. The printer gets up to temperature before starting. I’m using the medium speed Standard profile.
Is the start code not ‘priming the pump’ soon enough? Filament not hot enough to extrude?
Any advice for how to get the printer to start sooner?
