Yesterday I tried some new custom nozzles that I ordered, very short, to put 10mm high capacitors, and it has worked very well for me. It requires a bit of study, design the PCB properly and order the positioning of the components, all to avoid collisions between high components, even other nozzles with high components already positioned on the PCB, because the Z axis only moves 10mm.
I thought I would have problems and it would not be possible, but no, it worked for me, I'm very happy. I already have several PCB that now with these very short nozzles, I can mount 100% of the components with the Neoden4.
I just need to try to add a 0.5kg weight to the 24mm feeder peeler to see if I solve the problem of peeling the tape, and all my problems will be solved. It is hard to start this machine, that everything works well and can put all or almost all the components, but it seems that in the end the problems are solved.
The great design error of this machine, is that the Z axis only moves 10mm, if it moved 15mm, the machine would be perfect and could put all kinds of components without problems. Also some feeders are very badly designed, the peeler of the 24mm feeders has very little strength, and the 16mm feeder has a hole for the outlet of the tape too narrow that prevents using some components.
Some small bugs in the program should also be solved, and one that is quite serious, although it has a solution, is the misalignment of fine pitch chips (LQFP100, LQFP144, etc...), when the nozzle has to rotate them to position them on the PCB.
