My K40 seems to be losing power. It's struggling to cut 2mm acrylic cleanly at 15mA, 10mm/s speed.
In the past I am sure it would cut at 10mA, 20mm/s.
Its a few years old, but doesn't get used...

Complete fusion 360 newbie here...
I have a single fusion 360 assembly drawing, with many constituent parts (bodies).
What is the easiest way to get all the parts layed out into an stl file for...
Hi Craig,
The vid I was looking at was last year by Physics Annonymous, he's gone on to make a new UI for Mach 3... Not that that help fix any bugs or glitches!
Does LinuxCNC have many...
Hmmm ok. Just watched youtube video called 'Mach 4 Sucks'!
Maybe the UCCNC is worth looking at?
Thanks Craig.
My machine has magnetic limit switches at both ends of X and Y and a single one on Z. So doing a Ref All at the start is obviously a good idea.
On my setup, Mach 3 does seem to...
Ah OK, I had assumed Mach 3 could check absolute position... No plug in to do that either...
As an option, is it possible to to add a home reposition check into a CNC program?
It's early days...
I have a DIY gantry machine and I have a stack of resolver position sensors (contactless rotary encoder 4096 steps per rev).
After an incedent where my machine somehow lost it's position,...
Hi Daz,
Not sure if its a clone or not. It came with the machine...
I can try a re-install of the plugin and see what happens...
I think this is an issue with the UC100, once it locks up, it wont move with any keyboard or onscreen MPG. In step or continuous modes.
No sure the best place to post this, but I have a custom made gantry mill running off Mach 3. When I set the on screen MPG to step mode, the mill sometimes just stops moving.
It appears to work...

Thanks guys.
I have it sussed now. The M6 tool change macro was confusing things. I didn't write it (it's a previously owned machine and laptop) and I don't really know what it's doing, so once I...
Are the electronic edge finders with a small ball bearing on the end any good?
I'm talking about the 'cheap' ones on Amazon! Not a Renishaw. About £25.
I have a new (to me) gantry type cnc router which was custom built. It has magnetic limit switches on all axis but I found that they are all wired together to pin 10 on the controller.
Is that...
I have a gantry type router (custom made) and I want to set up th Z axis.
I think it has lost the correct Z position as Z zero is about 80mm away from the Z up limit switch.
Whats the correct...
Thanks, I'll look into that.
I wondered if there was a simple WYSIWYG front end to MACH3 where you can drop and drag holes, slots, circles etc and the CNC will cut them?
Yes, I just downloaded it last night! Seems to do just about everything including having Path Workbench to do the post processing.
Little bit of a learning curve, but I guess it's good to...
I usually draw stuff in Sketchup8. I started to learn Fusion360 until it went web-only and subscription.
I have a gantry type CNC mill, with MACH3.
I want to do some repetitive hole drilling,...
Thanks. Will check them out too.
I found another 'real' manufacturer, Liaocheng Hongqiang Electronic Equipment Co., Ltd. They appear to have a UK agent too. A massive range of laser machines...
Thanks for the info. Will check them all out.
Hi All,
Just begun looking into laser engraver/cutters after playing with a 'toy' machine for a bit - managed to cut stencils with it, so it did it's job.
A 600x900mm size 80-90W machine seems...
Thanks guys.
I am setting up for flood cooling at the moment.
Thanks again Craig, yes I mis-read confused surface speed with feed!
I have a demo of G-Wizard and it's showing me a surface speed of 274m/min, rpm 6400rpm.
If the 'finish' slider is on finest,...
Hey thanks Craig.
Does my feed speed of around 500mm/min sound right?
The video is interesting, I'd always thought that the very front edge of the tool is there to initiate splitting the chip...
Hey thanks Craig.
I'm guessing that your quoted speed is mm/min and not m/min!
The video is interesting, I'd always thought that the very front edge of the tool is there to initiate splitting...
Thanks Jim.
I will try some WD40 or a small amount of suds oil/water mix.
The finish was great for quite a while but suddenly changed. (pics in worng order, so inital finish is on the right!)
Some help needed for a newbie (to CNC).
Machine is a small gantry router. (not a bendy chinese one though!)
12mm 4 flute solid carbide end mill.
0.1mm finishing cut, 10mm wide, across a plate...
Very interesting! Thanks.
That design looks like it only has one rail on each side for the Z axis.
I think I would have joined the uprights together across the top of the gantry to make it...
Anyone ever built a gantry machine with the z axis rails and ballscrews mounted at the ends of the gantry and the spindle only moving in x along the gantry? (The whole gantry moving in Z)
I know...
Agreed. I've asked them for a quote with 1610 for x and y...
