Hi Guys, another even if very crazy solution is a screw without thread. Bearings run tangentially on a shaft or in a tube, are disposed inclined and tightened against the pipe or shaft. In a round pipe which is quite simple in a square tube is slightly more complicated, but not impossible. http://ww...

Hello, You can do the same thing with two belts, the stiffness of the belt would prevent from tilting of the piston transversely to the belt as a belt on the right and a belt is attached to the left side of the piston. Then both belts must only run synchronously, the piston is forced out. Best wishe...

Hello, I have a proposal for a Z-axis: You could work with a pulley like that. You can use a timing belt as a rope. The belt could run in slots. This could be generate by plates that is mountet square in side the The belt could run in slots. This could be generate by plates that is mounted inside th...

Yes you are right,
the 1001 is a monster. For a small test printer XAAR 128 would be more interesting, and much cheaper. I am also interested in the potential that you win by an own drive.

Hallo Wonko, I know the Xaar 1001 well. The inks have a return, therefore, the nozzles do not clog as easily. It is also more expensive. I have the problem with the printhead that I would like to have more ink per drop. But the XAAR system provides a maximum of 8 gray levels. Could your driver creat...

Hello,
are you sure? I understand that it can not operate at the same time the two printheads. Whatever that means.
It would be great if it works. I look forward to your results.

Hello,
the L6452 could indeed significantly reduce the PCB. But you will probably need two L6452 to drive a HP45, right?

Hello Wonko,
XAAR print head looks just lovely. Can you vary with your hack the waveform of Piezzos?
To my knowledge, you need relatively high voltages for driving the Piezzos, How did you do that?
Can you also produce greyscale with the print head?
Best wishes

Hello,
I would only point out the problems that cable should be bent as seldom as possible. I would try the end switch not to be mounted on moving parts. However, it may be useful to define the starting point of swatches by a backdrop and a switch.

Hello,
what's with the A6812 20bit, or the A6818 32bit. It works with 3.3V logic voltage.
I have found no information about the production status.
Here is a distributor:

What is the end stop used for?
