The steppers seem to be working just fine, although I don’t have a physical load to put on them at the moment they seem strong enough to do the job.

If you want to be extra careful, you can check the resistances to ground at the pads where the main chip will be soldered on.

Genuine Thbah Stepper Motor Drive IC Replace Toshiba Tbaqh | eBay

I also got to work at my own pace and buy a piece here and there as finances allowed rather than trying to scramble stepper come up with big ticket money all at once. That could be handy.

Page 2 of 3 1 2 3 Jump to page: Stepper motors CAN be smooth! Let me know if you have any thoughts on how it can be improved. Would love to see a pic of the machine as well.

Not that I’m complaining of course I ended up at about 1. Tags for this Thread almostdownfarnext.

THB6064AH THB6064 Stepper motor driver chips ZIP25 Best quality

I somehow totally missed the chart in the schematic, LOL. Stepprr what I get the drive current on that error output pin on the chip is weak and the transistor is used to pump up the current which both drives the LED brighter and allows it to use a pin that is not-quite PMinMO compliant to send the error signal back to the PC? Tell him what’s missing! Results 25 to 33 of How many tools does it take before a simple task becomes a project?


I’m not dead yet John, that is a great analysis and jives precisely with the observed behavior! Here is a video on the assembly.

Results 13 to 24 of Preliminary Inspection and Test: There may have been one on the website but I missed it. It’s effect with also depend on the motor. So far so good, nothing smoked yet, LOL I have a question about the decay and step settings on the though Power off and prepare for finally assembly. I’m curious what made you decide on our drivers over the KL electronics offered by Grizzly? I can take a pic but I may have to bring in my “real” camera for it to be any use to you.

Amplified Error Reporting For Rev 1.

Just like to support open source electronics? I also haven’t double checked it yet so take it with a grain of salt, LOL. I’m working with Luc on that now. I’m the Tool that turns a simple task in to a project. The “Optional” section of the board Which means they are opposite of what is in the chart in the datasheet. I’m willing to pay for help, please refer me to a qualified consultant” “No.


I had looked at some other options all in one kits, packages, cheapie eBay stuff and mostly the looked like it would be just stpeper behind in power and specs but had the advantage of being a modular design plus I was looking to dive in to electronics more at the time as well. What motor voltage are you running? I think breaking out the section stdpper the optional stuff to it’s own section separate from the main assembly directions would help The steppers seem to be working just fine, although I don’t have a physical load to put on them at the moment they seem strong enough to do the job.
