I've built and still use a machine in roughly this layout although my components are not near the quality proposed here.
When in use it's footprint is larger than an equivalent moving gantry but...

Egads did I install an operating system or adware ?
Dear Microsoft:
Please allow me to run Fusion 360 and quit bothering with features and offers I don't want.
Is there a way to turn this stuff...

If 1 inch steel plate isn't up to the job the plate becomes stock for my larger mill, nothing lost.
My guess is something else will start deflecting first and the extra mass may do some good....

I abandoned the plan for a reason There's the germ of a good idea in there somewhere(?) but I won't try to defend the untested :)
My mill is in an enclosure so it's difficult to take a picture...

This may not be the problem but:
Try marking the position with a short tool like a centre drill and then rechecking the position with whatever you've got that's long and straight with a pointy end....

Here's a mod I started on my X2 but never completed. The idea was to have bolts or set screws coming in from the sides.
Obviously I've done no testing.

Out of curiosity I plugged an Arduino Uno into Windows 10. It showed up as a generic "USB serial device (COM 3)"
You may need to install the IDE or at least a driver. The IDE install offers a...

disclaimer: I rarely use Windows and have never used Candle. I'll assume Candle is a sender for grbl.


Since the Arduino has already been flashed with grbl I don't think there's any need to...

If it's a Kerk lead screw it will have some form of anti-backlash. You could ask the seller the screw/nut model # as Kerk has several.
My preference would be a ball screw over acme.

Oh I misunderstood the problem. This image shows work piece position being defined in FreeCad
It's a program to cut a square.

Cambam will have something similar. I looked at Cambam years...

I have no knowledge of grblgru but some experience with grbl and senders.
The concepts in linuxcnc and grbl are the same. There are:
Machine xyz coordinates which are set by homing the...

Yeah I've also seen weirdness from this website's software. Please don't feel obligated to reply, I don't post here for thanks, mostly it's boredom with my current reality. I got this in my...

I looked up the specs of a 3018 and read dimensions of 300 x 180 with a cutting area slightly less than the machine dimensions.
Is your machine larger ?

Table locks are the little levers that can apply pressure on the gib strips. Your manual may call them by some other name. Unlike the acme screws in your mill a ball screw has very little friction...

Your post covers a lot of ground so I'll just post some random thoughts.
That mill appears to be a variant (near copy) of the Sieg X2 mini-mill ? If I'm wrong about that the rest of this post won't...

I'm not sure how the term "lag' is being used in in the top post.
To measure deflection a dial indicator would be handy to narrow down the source. My guess is the v-wheels with their stand-offs are...

I think this book will include examples up to Mill Level 3. These are high quality and were distributed by Mastercam sales reps.

The information in this link is mostly Greek to me but Linuxcnc can do what you ask:

oops I named that file wrong.
5" x 10" should have been named 10" x 5"
10x, 5y
I think you figured that out :)

The attached file saves as Probe & Cut using the latest g-code ripper tested in both Linux and Windows 10.
If that file fails try a fresh download of g-code ripper.
If the fresh download fails and...

Scorch is the authority but he won't spot this thread unless you contact him. His email is under the help tab.
Why not simply ask the question ? You might get lucky.

Sometimes workarounds are necessary but only when it's proven things don't work as intended. Below 2 files are attached.

The gcode output of that svg from Makercam is...

My previous response doesn't offer much help beyond 'it works for me'. The problem is it's hard to guess why it doesn't work for you.
Tell me where to find the clip art and I'm willing to try. ...

I wouldn't consider that a critical dimension, give the bore a bit of clearance. The forces acting on that block are axial. As far as alignment, making that a press fit will cause more grief than...

That behaviour can be shut-off in linking tab lead-in/lead-out some-thing-or-other per tool path operation. I don't have Fusion on this computer so that's as specific as it gets :). There may be a...

This video is over 1 hour but the from 6:10 to 12:50 the current state of 3D surfacing in FreeCad is discussed.
To sum it up 3D surfacing is for test pilots atm.
