Connection between 1XD and iHSS57 stepper motor

Elena

Hi @dc42! Thank you. I have tried to cross the EN+ and EN- but the problem persists.

Probably best to leave the EN+ and EN- driver inputs not connected for now. When you get the motor moving, you can reconnect them and establish the correct polarity.

yes

Hello,
now it looks like the motor works, i simply didnt connect EN-

Hello Elena, i was struggeling with nsame problem, i was conecting first in Differential Signal for testing with 25cm long cable and it works without problem, then i was using longer cable around 2m and it didnt work anymore. Even this was a good cable for cain and with shielding.

Now i am using:

and didnt connect Enable + signal and it works.

Ok, now my printer is working but of course i didnt connect the EN- this means always on, i cant move x and y when printer is on manual, i am not shure how to conect EN+ and EN- to the 1XD board.

Can i destroy the motor if i change polarisation ? for en+ and en-

@FLSMichael my advice is not to use the common anode connection, but to connect the + and - signals individually for each of STEP, DIR and EN. That way the opto isolators on the driver will turn off faster. It's then safe to cross EN+ and EN- to reverse the enable polarity. Differential signalling works better over long cables than common anode, so you must have had a bad connection.

If you want to stick with the common anode connection, then connect EN+ from the 1XD to EN- on the driver. EN+ on the driver goes to the common +5V connection, and EN- on the 1XD will be left unconnected.

@dc42 ok I will try this

@dc42
ok, i have try now:

but it dont works, motor dont moves! LED goes to permanent RED

when i change EN+ to EN- and i start Homing then LED is permanent RED but motor is also not moving.

I has check the Rev. from my 1XD it is REV.1.0 may is this the prob?

@FLSMichael I am wondering whether the EN+ or EN- output of the 1XD board might be faulty. Do you have only one 1XD board in the system?

FLSMichael

@dc42 i have 2 of them both are doing the same, but not with shot cable like 20-30 cm.

Hi @FLSMichael and all, I have the driver now working with the 1XD. In my case the driver itself was faulty. I returned it and replaced it with a new one. I am using EN+ to EN+, PUL+ to PUL+, DIR+ to DIR+, and all the - are grounded together to the ground of the POWER IN of the 1XD. This seems to work well and I have a cable that is about 2m long. If I have time I will also try the differential signal connection. But bottom line is that the driver was faulty. Thank you all for your help, let me know if there is anything you will need know from my set up.

@elena thats sounds nice i am waiting for new cable then i am going to try that.
