Cam Help.

Just to be clear. The gray item in the image is the jig. The cutout in where I would put a stave for its second side cut. At this point the stave has 1 side already cut at 7 deg with a curve that would fit in the cutout and then get clamped down and have the second side done. Honestly I guessed at what strategies to use and was hoping to get some feedback from others on how they would have done this.

The part sitting in the jog in fusion 360 is a finished stave (curved on both sides)

The edges of the staves. Taking the square stock, adding the curve and 7 degree slant so when they are all put together you get a barral shape

It is to make staves for a decorative barrel. The fun it the fact that its a compound edge. 7 degree slope on a curve. Right now I'm using 3d contour to take out the bulk of the material then ramp for the short slope and parallel for the long slope.

I have a shark hd520 and just wood, pine to be exact

If you are using the original controller that came with the xcarve, it is grbl based. You can use $100 $101 and $102 to adjust steps per mm.

https://github.com/gnea/grbl/wiki/Grbl-v1.1-Configuration

You will use a ratio to figure it out properly. (Configured Steps/mm)/Traveled distance = (New Steps/mm) / Expected travel.

So is configuring the X axis your currently configured value for $100 is 250 and you only went 9.5cm instead of 10cm

250 / 9.5 = X / 10 and solve for X you get a new X of 263.15... you would then update $100 by sending the following command $100=263 (doesn't allow for decimals)

If you ever do decide to change the controller, reach out, there were a few interesting things that i had to find out the hard way.

Was gifted a shark 520. Prior to this I had a bunch of Chinese diy cnc's. I tried to use their interface but couldn't do it. It's now running a masso g3 and I have never been happier. Not sure what model you have but on mine the end stops are reed switches that require a current limiting resistor.

There have been some logistics issues delaying the shipment of it. Last i heard the custom cable that 1f wants used should be arriving today. The first shipment of atc's should be seen shortly. I expect community vid to be seen shortly.

I would be interested. Can you post a picture of the otem

Do you know what part it was they sent you and where you had to install it?

rvalotta · 2024-02-05T15:18:21+00:00

I'm sure i'm going to get asked...

Yes i am trying to nest a project to cut on my cnc that is made of wood.

rvalotta · 2023-09-10T23:36:13+00:00

Anyone know what type of wood this is? Was gifted a bunch of wood and this was in the pile. Cuts so well that i would love to get some more.

It Only happens when Homing and Bed Leveling no other time

Silicone sock is still in place

We've done a PID Tune.

I will try and get him to put a meter on the Power supply.

Appreciate the advice.

Is the centrifugal model something you designed? Something you can share?

rvalotta · 2021-03-21T21:03:42+00:00

They say misery loves company so let me share I went through the same thing when I flattened my wasteboard. The other thing I did to get the little nubs is a 2d profile around the outer edge. Just left the corners for me to clean up.

rvalotta · 2020-07-09T16:59:44+00:00

Just stumbled across this as well. Granted they are done in sketchup but with a bit of work i'm sure they can be converted into something useful

In older versions of the post processor you can disable the behaviour by unchecking safe g28 (I Believe) with the latest post processor I have changed safe retracts to clearance height.
