summa s120t cutting problem

[Split76]

Hi!

My cutter is not cutting right.. missing parts are not in same position if i cut 10 side by side.
I changed cutting strip / knife just in case, but didn't expect it to help.

Could it be worn coil? Any help or advice would be nice, i'm going to service the cutter by myself anyway.

Quite simple machines to change parts, but i just don't know from where to start
Luckily i have F as a backup..
I attached a pic about the problem

If a new knife havent solved the problem, you should try to adjust the coil.

Find „coil setup“ in the cutters menu, select knife landing, set the value to zero and increase it step by step. Watch the knife tip until it is lowered down to the cutting strip. Add another 4 units and press enter.

try frank 's idea first he knows these machines well
dont know which way round it was cut but the missing bits appear to be in alignment indicating a main cross cable issue can you hear or see it tap up and down

try blowing some compressed canned air in the cutting head area, could be a buildup of dust.

Looks like really deep cuts(?). Are you trying to go all the way through, or just the top layer?

Thank you all for your answers, I´ll try tomorrow. Cuts are not too deep, it's heat press material. Tried also with lots of circles and normal vinyl. Didn't cut through silicone layer but the problems seems to be the same. I'll adjust the coil and try compressed air. Both are good ideas i think
