I just purchased a (used) workhorse. I’m having several difficulties.
First, inova-1800 just doesn’t want to stick to the bed. I’ve read elsewhere on this forum that inova-1800 sticks to anything. I’ve tried with glass up and with and without glue. On the off change that the problem was the filament, I loaded the same filament on my Mini II and it stuck just fine. I took the filament that had been working on the mini II and put it on the workhorse - a small one layer test print stopped sticking to the bed about half way through.
On a rare occasion where the print stayed stuck to the bed, it came out crappy at best:
Part of the problem is that the Inova-1800 profile on the workhouse says “not supported” and won’t work. I modified the PETG (IC3D) profile to match that unsupported inova-1800 profile just to get a profile to work with.
I’m not sure if it is an issue or not but this workhorse has a IT Works 0.4mm tool head on it. I am willing to try the 0.5mm SE tool head from my Mini II if it is compatible. Otherwise, I would gladly trade it for a standard tool head for this machine.
