for small PLA (so 40x40 mm) things, no. Bluetape and other surfaces are fine.

most larger things and non PLA yes

100mm on Blue Tape would be ok.... once it's setup right.

Gluestik on glass will work, its what I use.

You have to get the plate level, and use the 1 piece of paper thickness to set the nozzle height.
It will be unforgiving to nozzle height. Too far away and it will curl. Too close and plastic wont come out.

You will be limited to PLA. I have managed to get a TPU to stick but it was only 1 time and a very small part test.

ABS and PETG not going to work.

Good luck.

RigidInk PLA+ printed on blue tape sticks brilliantly. I've printed 400mm long parts using this combination.

Maybe can be fixed in software.

The firmware may have a preset priming value, but the slicer may feed some too.
Check the slicer first.

Check the "start gcode" section of your machines settings (at least in cura).
Lookup G92 and G1 codes.

I have a pair of tweezers or scissors handy, I do all my warming up 10mm above bed, and when it hits temp or around 185c I start purging 10-20mm on extruder and remove, then hit print...and if any more come out remove as it's moving to zero
