Good idea, I tried setting the feedrate low, but no difference.

Then I measured with my oscilloscope. The Tang outputs all work as intended. Direction, Enable and Step. Focusing on Step the signal looked really good no matter what feedrate. However, the issue is the logic converter. I am using the Texas Instruments TX0108E. www.ti.com/lit/ds/symlink/txs0108e.pdf?ts=1730734048833 But the step output signal is only 0-2.5V and not the intended 0-5V. Sometimes the output goes up to 5V, but not very often. The enable and direction pin are a bit more reliable but even they are not always 0 or 5V and are sometimes in between. I thought I made something wrong or the level shifter are damaged, but found this video. The issues he has are very similar to mine and even all the comments under the video don't give an solution.

Anyone an idea how to get the TX0108E working correctly ??

I ordered last time some of those as well, the order is supposed to be here this week. I have 1x 3.3V to 5V and 2x 3.3V to 12V in the order. I wonder if i can use the 3.3V to 12V with just 5V for the stepper driver www.aliexpress.us/item/3256803586254541.html

 

Hey Tom good day to you, my names Tom as well BTW
(theres never enough Toms on the job! haha)
So THCAD5 would be for a divider board with a 0-5v range and thc10 would be for a divider board with a 0-10v range correct? So I will need to see what the voltage output of the divider board on my hypertherm is if there is one or purchase a divider board and wire it up to the raw arc voltage correct? I apologize for bugging you guys with so many questions but I really don't want to order the wrong components so it is very much appreciated.
