In your case 300 steps x the microstepping value you setup onyour drive goes into STEPS/REV in the Wizard.DocsMachine wrote: ↑Wed Dec 20, 2017 2:56 pm-Therein lies my problem. The motors I was sent are three phase, not four, so they're 1.2 degree, not 1.8 degree, which means they're 300 step/rev. No problem so far, except the drivers have a set of DIP switches on the side, and a chart silkscreened on the top, to set microstepping. They came set for, and are still set for, what the chart calls "default"- but it doesn't specify what "default" is.cncman172 wrote: ↑Wed Dec 20, 2017 9:54 am Most steppers have 200 Steps/Rev, however when you add micro-stepping you need to take that multiplier into account. When you have a driver that uses micro stepping you need to know where it is set. For example if it was set to 1/8 then you take 200 * 8 = 1600 steps/revolution. Some where you should find a little chart on the driver or a manual that tells you how to set the micro stepping using the little dip switches.
The next setting down from that is 800 steps/rev, then 1600, so 'default' would logically be 400, right? Except these are 300 step/rev motors- meaning the machine travel will be about 1.3 times faster than intended.
But that doesn't make sense. These motors have encoders, so you'd think the drivers would "know" if the motor were 1.3 times out of position.
Then again, Marty's video, if I understand it correctly, suggested I should but in the encoder count number in the step/rev box in the Wizard, not the motor's inherent steps/rev.
Which is why I have to ask. Neither my motors nor my drivers are quite the same as the ones shown in Marty's video, despite the fact I ordered them straight from Automationtechnologies.com- they're close, but not quite.
If it helps, at the moment, I have the encoder number in the Wizard steps/rev box- that is, 4000. I have 15 as a turns ratio, since it's a 5TPI screw and a 3:1 belt reduction. When I jog it manually, the carriage moves roughly three times further than it should- the DRO shows something like 0.315" or so, while the carriage has actually moved about an inch.
I'm sure this is all terribly simple to those of you that have more experience than I do, but at the moment, it's kind of frustrating.
Doc.
For example if you setup 10 mcrosteps, then 300x10(drive microstep value)=3000 step/rev.
The spreadsheet works, just change 1.8 to 1.2 in Deg/Step (I changed it in the screen shot)
Keep in mind the higher the steps/per, the lower your rapids become. Don't go NUTS with the microstepping.
Try using the 400KHZ Steps feature in Tab 4, if your drives will take it, you can increase your MAX RATE Settings. The software will bark at you if you try to go to high and set the max for you at a certain point.
Give that a go. Let us know if that helps.
