Re: Is an oscilloscope necessary?

I bought a SIGLENT 2 channel 200 MHz scope on Amazon to use in trouble shooting step/direction problem. Cost $400-$500. Worked fine after a little time to figure out controls.

Re: VFD Article

The Belden article touches on the issue of single ended grounding vs double ended grounding. As I recall, it's been couple of months ago that I read it, they justify the double grounding because of the size of the currents involved. Most of my experience has been with small to super small signals an...

Re: broken acorn encoder plug?

I would take a step back and remove the encoder cable from any cable bundle and separate it from any high current electrical items. It could be that the cable movements simply put the encoder cable in a noise position.

Re: Program not matching Machine movement.

Suggest you do the simulation run in Fusion 360 to verify that it is doing what you think it should. Then I would suggest you double check the post processor you are using. I'm not a g-code expert by a long ways but your code doesn't look quit right to me. Also read up on G2/G3 g-codes, they can be ...

Re: YouTube video showing how shielded cable works

My machine is close to a highway with just a large window between electronics and passing traffic. I recently installed cat-8 ethernet cables between the computer, acorn, and ether1616. This reduced the number of communication errors from maybe a few per day to less than 1-2 per week. You should con...

Re: encoder pin1 = N/C, RLS encoder

Could you let us know the exact model RLS encoder you have?
