Just sorting my electronics for my 1000 x 1000 Sphinx Laptop —-> Arduino —-> DQ542MA —-> Nema 23 (265 oz) First off thanks for a superb connection guide kyo. However I have a problem when doing a dry run set up on the bench On my old dual belted ox I could quite happily run at 4000mm min all day long. But I tended to run at 3500mm minute However not so on the current setup I have tried to run at 4000mm (loose steppers on bench) and it ramps up to speed and ‘stalls’ Not that I am going to run it at that speed but still happens at 3500. At 3000mm min it will run fine and have done a full 30 min dry run on the bench without issues. I have tried different microstepping with the same results. And happens on all controllers / axis / steppers I am thinking that although the steppers are more powerful the pps is lower resulting in the problem I’m getting. Pics of old and new steppers attached.
Whats your supply voltage? Higher voltage allows higher step rates. DQ542ma can handle up to 50v. Mm/min without steps-per-mm is also hard to judge, if you have a high steps per mm count still configured, your mm/min estimate would be off too
OB 24v psu Tried it on 1/2 microstepping and 1/4 and 1/8 on the dq542ma with the matching steps / mm with no difference. I have noticed that on the spec sheet all drivers will cope with 5000 pps.... except the 2.8a 265oz which is 2500 pps Could this be the issue?
Make sure you have enough power to run the motors You could have a noise issue reconfigure your pulse timing if you can
