Hi all. Reading a little here and playing with the configuration finally I have movement in the axes !. As for the Y, after trying and trying, I have isolated that it is the driver's problem, so it's time to buy. What do you recommend? is for a Nema23 stepper of 425 oz. While I will continue advancing with the limit switches and the adjustment. Thank you.

For cheap drives get a DM860 it will give you more room to play.
For dirt cheap get the TB6600 but beware there are new drives claiming to be 6600 but are a different TB with claimed 4 A, and in the datasheet that is the absolute max rating, meaning you get 2.5A or thereabouts.
For the best drives money can buy get the Lam Technologies 1044 or 1076, expencive but rated as RMS and very configurable, just do not forget to order the dongle to program them or you get stuck with 1A current.

Thank you again, Tommy, for your help :laugh: . I think I'm going to decide for the DM860, I think that to begin with, I am the perfect balance. The cheap Chinese Tb6600 I already have and the experience is not pleasant at all, one has broken down, another seems to work when you want ... if you spend well you buy once ;)

The DM860 that sell in Chinese pages are reliable? Here in Spain I do not know where I could buy them.

I would be very grateful if you put a link to the DM860 that you say, looking, I see a wide range of different models, from blacks with a multitude of letters (DM860, DM860A / D / H ...) to blue ones that are 32 bit digital (2DM860) with their respective letters too.

Wantai or Leadshine, but Leadshine come very close to Lam Tech in price, so much beter to get Lam.
I do have 3 wantai 860 on a machine working perfectly for over 2 years.
There is a wantai shop in germany on ebay, so try to find them as there is not tax when you order from them.

This can be the DM860 that you say?

when you can Tommy, thanks. eBay would be the best option for me (price and delivery)

That first link is suspicious so stay away from it, DM860 should do 5A or 7.2A peak, not 2A as this one.
The second one is also suspicious from the price, the Wantai ones cost nearly 60 Euro a piece.
Searched ebay.de but could not find any of the wantai shops in Germany any more ! Something must have changed there as i did order them from Germany and they were shipped from China, arrived in 10 days with no customs or tax.


Found them

Remind me, what exactly do you need them for ?
Most probably a TB6600 will do just fine at 10$ a piece. Although i did order some lately and got some much weaker ones in the same package using a diferent and extreemly small IC from Toshiba, did not test them yet as i fear i might throw them in the bin ! :)

They are to handle a Nema23 of 425oz, I burned a tb6600 by a careless and another thought that it worked badly, but doing tests and investigating I have come to the conclusion that what is wrong is having put pulleys Gt2 of 20 teeth in X and Y that are the axes that are giving me problems from the beginning, I have tested both drivers in Z that works with thread of balls (1204) and both are perfect. How did you say the other day I'm learning a lot in a short time, with that relationship by step the microsteping should be brutal to approach 0.1 mm even
