Good Afternoon Mark; Can you please give me a bit of a heads up on setting the current in the X, Y, Y1, and Z, axis of the Black Box Controller. After a bit of COVID Delay, I have finally got my CNC Machine moving but the Motors seem to be quite hot while they are idling. Too hot I believe but they still drive in the correct directions. While I am trying to calibrate both the X and Y axis, step 2 seems to continue on and I have to hit the emergency stop button to save damage to the machine. I can manually move the spindle in all directions (using the continuous control option) but when I try to make it move in the Jog option of,100mm steps in any direction the unit continues to run on to possible destruction unless I activate the emergency stop button. I have swapped the selection to the Jog and am able to make the unit do so but: When I try to make it jog 10mm it actually jogs 100mm; 1mm it Jogs 10mm etc. etc.in fact it looks like there is a Multiplication / Division factor of 10 involved in this manoeuvre. Could this be a setting in the programme or is it to do with the current settings of all of the axis? I am using 24 tooth cogs on my machine and I noticed that there only appears to be selection values for 10, 16, 20, and 30. Is there any way of changing this so that I can select the number of teeth to suit the cogs that I am using and could this be the reason for the apparent variation in the jog settings. Thanking you all in advance Kevin Lazarus.
Thanks for that Peter I will try that setting. I think I said in an earlier conversation that I would probably be back in touch and it looks like I was correct. Do you have any suggestions as to the current setting of the Stepper motors and is there a method of actually measuring the current or is it just a bit of suck it and see mentality?
Factory default is good for 99% of users. No measuring needed. The adjustment scale is "humanised" - quarter turn or so. Unlike lesser drivers where you have to turn the pot half a degree at a time. Ours has been engineered to be logical. Overheating, turn down a bit. Stalling, turn up a bit
Sounds a very sensible way to approach the problem. Thanks very Much Peter, I will give it a go in the morning when I am a little more receptive to variations. I will keep you informed as to how it goes. Cheers Lazzo
