They are two different aspects unrelated. Inductance will determine max speed before torque drops off.
Closed loop is simply error correction. With closed loop you can run closer to the limits,...
Jim, I see how you you did that. Thank-you this will come in handy now and down the road.
The attached F360 file is just one example.
I have a piece to cut larger than my table so I setup to "tile" cut with two operations. I'm using a 2D contour operation setup for three even step downs on my DIY CNC router.

I'm not using Mach3, but G code is G code right? The following might help if you can figure how to implement it.
I use a similar setter.

It was described in a white paper from Texas Instruments I found online. It dealt with business machine (printers, photocopiers etc.) stepper noise.
As a follow up question, I have 5mm lead...
...or so my wife says.
I get a pretty good whine from my DIY CNC router, the dog definitely notices. The stepper motors are silent at stand still, but in motion whine proportional to the rpm. ...
For epoxy rail leveling I would check out this build, post #8 This gentleman shows some mad skills.

I initially designed my DIY CNC router with 1605 1500mm ball screws. These were inexpensive foreign made rolled C7. No complaints.
Now I want more ipm/speed so I started looking for similar...
Perfect, thanks for that!

I'm looking to correct for some design issues. For a small cost I can double even triple my motor speed. However if I can't take advantage of the speed its no good to me.
What is a good...
I would assume so, thickness helps. But more important for twist/torsion is the effective cross sectional area and internal construction.
It's not pretty but in my design (18mm BB 11 ply) the...
I'm looking for ideas for a monitor boom or arm that can mount to my DIY CNC table or the table stand. It can be DIY or store bought on a budget.

I'm using a Linux Mint distro/ISO put together by a member of the LinuxCNC forum. Came complete with Mint and LinuxCNC 2.8 premptive (I'm running a Mesa ethernet card). Worked right out of the box....
DOC 6mm, 1200mm/min. 10-12krpm.
My feed rate is limited, my poor machine design. I haven’ t tested running any faster. I could drop to 8krpm but that is the low limit of my router, I don’t know how...
I read somewhere that 1/4" shank carbide bits tend to ring.
Boy do they ever! I'm using an Onsrud 52-285 (upcut 2-flute 1/4", 1/4 shank) in 3/4" BCX plywood.
What is the ringing telling me? ...
In the "for what it's worth" department, I went with the Dust Deputy for my 2-1/4" shop vac.

I'm looking for recommendations for an inexpensive touch plate for setting the Z axis on my DIY CNC router.
In my searches I see a lot of hockey puck and plate style devices that don't seem to...
I've only started cutting with my DIY machine and my shop vac filter is already clogged. Mostly MDF from surfacing the spoil board and some miscellaneous brackets.
So I'm looking to add a cyclone...
I'm going with a 2-1/4" (57mm) vac hose to my shop vac ~20ft long.
My table has a 4x4ft. stroke. Have any advice for suspending the hose overhead so it doesn't tug on the shoe or smack the...
Speaking of hoses. What size hose are you using now? That one in the picture looks small, does it step up in size? Are you using some sort of shop vac or a real dust collection system?
My DIY CNC router is fired up, spoil-board down and surfaced, and what that has taught me is I REALLY NEED A DUST SHOE ! :(

I have a ~1/2 gallon of Titebond II. My only concern is the open time, It sets up fairly quick and I have to coat a 4x4 ft spoil board.
Do you coat both mating surfaces or just the one? Have you...
I have two sheets of MDF router-ed and T-Nuts installed ready to lay down.
I read some people use Gorilla glue.
I was planning on using contact cement. It's what I am used to using with...
Yes got it taken care of over there with an event handler. :)
That being said Fusion must be doing something different when I group tool paths into a single file vs. kicking them out each in an...
I must have enabled manual tool change in the initial setup under 360. I have three tool paths, 2 with one tool and the third another. Oddly only the first tool path had a M6 command.
I think...
You might be right, pausing on T1 M6.
I'm running LinuxCNC "Axis" GUI driving a Mesa 7i96e card. I'm not sure if I set a tool change mode. I'm not getting any message dialog to indicate a tool...
