I question if you are improving or adding options.

I think I know this. Go to post Process in Fusion 360 CAM , under Program Setting there is a list of stuff, scroll down to G28 and set to no. Every time I do a new part I have to set again.

I guess it depends if you want to build a CNC or build clocks.
As far as bed size I would want about 3 inches all round the part I am cutting out. Next if you are doing clock gears will you then...

Dumb question if you rotate one of the parts 90 degrees do they then line up?

I like it. Also if you put in a 2 inch long bit, Do you have enough height/travel room, the Z rails will hit the Z axis stepper motor plate as a limit.

I think there is 2 question here, what is the best Cad and what do I need to know. About 10 years ago autocad had a great 2d package but were lacking a good 3d Package, I thought they would go under....

No, did not 3D print.
I did machine all the black parts on early rev machine of tis CNC plus some drill press, I think the material is ABS it does not like to be machine it melts, if the bit cuts to...

I did go to store bought coupler because the rubber tube started slipping, what I bought.

I can not believe it been 3 years since the last updated.
Well I did think of some changes to make it better.
I will start with the RouterZip , the bearing went out when I was cutting Aluminum. I...

So you need a 50 v power supply and different driver or you need different stepper.
Now I am going to go against the wisdom of the board but I have found the threaded 1/2 x13 rod workable for a...

It hard to say with out a design to look at.
I used these bearing 608ZZ VXB Bearing Search Results | Search for Bearings Today little cheaper but they are 8mm ID.

Do you have a G28 in code, remove it.

I know you not using Mach 3 but there is a config setting in there that is I J mode, I have a chose between Absolute or Inc. So I would look for something like that.

Did you rezero after each run? If not it looks like you losts steps in the x direction. with the pattern repeating I thinking the stepper are doing what they are told. I would slow down feed speed...

I like KHOUJ idea about getting stepper to lock
I see 2 things on doc you posted. J8 needs need jumper on pins 1,2. and JP 1 needs jumper on pins 1 , 2 . This was the kind of stuff I miss when doing...

I had problems when I first connected my CNC up. It took like a week to find the right combination. I ran in to a line that was a enable signal that I over looked. Had to set it in Mach 3. When in...

See this why I did not think I knew enough to be a tutor. As always I do something the hard way.
Question If I have a JPG file How do I get a .svg.

I do not know fusion well enough to tutor someone. But if it was me I would get a picture that is head on. then I would import the picture into Fusion. it can be sized in fusion, to what ever size...

I was thinking that the motor signals would go through, I agree for switches they would be fine.

I use these controller and I think it is the only place in the USA to buy. I have had mine for over 2 years and am very please with them, no problems.
James may post and let you know if there is a...

20,000Hz???? The board Spec. Limit Conversion Frequency:20KHz is that fast enough????

Some time they will crack and the wire will not be broken.
That physical size is most likely a 25 watt, you can get the 50 watt and wire it to the board if you have room. it will not hurt anything.

Dumb question does it still measure 100 ohm? if it does, it is not the problem. It still need to be replaced for long term operation..

You have a big learning curve in front of you. I would hold off buying a lot of software until you need more. You will need a control software so get it (Mach or another ). If it was me I would learn...

I saw this in another post, 80 degree C or the wire isolation and rotor-magnetism will degrade, When I saw your post I was thinking 60C to 70C, this is what I see on most electronic parts. When I...

I would go to a 1/2-13 all thread for lead screws. That should get to you 35 ipm. Do you have the most power supply that you can use with the current driver that you have? I have 1/2-13 all thread on...

I am thinking that they bought the CNC and hired you, so they have spent the money this year, So shut up and do the job. Yes, you should have a CAM program. If it was me I would ask if it would be...

I do not know anything about Solder stencils. But some things that always come up are cost and corrosion and any electrical operating spec that need to be addressed after assembly.

Looking at the picture of the circle cut in the wood if side to side is the X axis and top to bottom is Y axis I would say the X axis is the problem. I would guess the ball screw is the the X axis...
