In your opinion, should I leave the db25 shell isolated from the logic ground on my PCB? PCB grounding is quite the ambiguous topic for me.



Hi John, thanks for the nice comments.
Not...

John,
Your info has been most helpful, thanks a bunch!
And you too CoAMarcus, chimed in as I was typing here it seems:) I appreciate the attachment, will have a look shortly.

I've been working...

Nice, thank you...my first quick glance looks like it may answer a few questions once I study it a bit!

Perhaps Gecko may provide something similar regarding the current model, that's the one I...

sorry...

but WHICH circuit diagram?

Greets,

I am working on designing a custom PCB to interface with a G540. The intention is to drive the G540 from Arduino and GRBL, just as an alternative to my current MACH3 setup which works...

Hmmm...interesting, I came here to look for advice because I had the same problem. Well almost. I have been using my router for maybe a couple years now, and had the red led fault error present...

interesting...didn't realize just how substantial the higher voltage affects torque @ given rpm.

guess I will have to get a bigger power supply or just live with the low acceleration. I will set...

So might I assume that the one current rating given for my motor in the linked .pdf of the OP would be the rating if the motor is used unipolar?

I have tested voltage on my PS while under heavier...

I am using a converted 48 volt switching power supply from a server.

So if I used a current set resistor to set the current 1/10 of the original 6 amps, to .6 amps, I would still be able to get...

I have been driving this step motor:

...connected bipolar parallel, for some time on my diy router table with good luck. However, the motor...

Hi Jim, thanks for chiming in........I would be interested in both the how-to of making the hand torch machine operable, and to the exact model of machine torch that fits the powermax45. Do you...

Ok, sorry, still lots of confusion:

It looks like your bladerunner system, hardware-wise, includes steppers, integrated drivers, a BOB, power supply, etc.from what I can tell.

I already have a...

Thanks Tom,
very direct answers....most likely I will be in contact with you sooner/later.

I plan to build a very small table, I simply don't have room in the garage for yet another cnc...

Hi folks,
I've somehow convinced myself that I cannot live without a CNC plasma cutter:banana: And I want to build my own but sadly realize there is quite a bit I still need to learn up on before...

Thanks for the links, at a quick glance it looks like I will enjoy spending some time there. Again, very well documented.

I just began researching extruders about 3 days ago, but your homebrew...

Looking forward to more progress.....!

I am grateful of your generous effort to provide your findings, document your work, and explain things in a straightforward fashion. Enough to warrant my...
