So what went wrong with this?

Post by Eddiem »

I spent a lot of time setting all this up and it is all cut wrong i can still use it but just not what i was expecting the holes are not in just the right places i wanted them to be for what i had planed out.

I cut Bench Dog holes for a new hold down system i am working on. See photos.

I am including the VCarve file

All the hols ended up cutting in the wrong places and not filling the board all the way like i had it designed. See the VCarve preview image you can see the holes should be all the way to the end of the board the way it cut they are around 4 inchs in on each long side of the board making all the hole cuts off from what i designed.
The long side holes are designed to be 4 inch apart but they cut aroind 3 inch apart and none of the holes went from the front and back edge of the board like the preview in VCarve.

Also none of the holes went in as deep as i have it set to 1 1/2 it only went in 1 inch i had to go in and hand drill the main holes i want to use down deeper.

The board is 24x48 as is what i designed

I am including a photo of how this hold down works i am working on so nothing is sticking up and all is out of the way for cutting.

My boards i end up cutting are so close to the edge that i cut i can not have anything sticking up or in the way i end up hitting it.

Thanks

Eddiium,

I looked over the file and it seems that the file is correct. I would venture to guess that this is a post processor problem or if you are using Mach 3 some settings need to be changed. It looks to be the unit values are off if they are consistenly the same distance off and the depth is off. As usual, if the preview is correct, if the machine is set up correctly, it should cut correctly.

did you have the panel oriented in the right direction when you cut it?

You vcarve file shows landscape and you machine shows portrait.

Yes it would of cut off the board the other way.

Then count the rows on the cut panel. There are 12 rows. On the file there are 12 rows.

On the left side the columns of holes is space over from the edge. On the right side they are very close to the edge.

The v carve preview looks correct. I presume you moved the spindle to the center of your table and zeroed it...with no offsets. The other thing I would check is your x and y calibration. Does your machine move six inches when the G-code calls for it to move six inches - if not, you need to calibrate you x and y axes.

The crv file has the job laid out in a 48" wide by 24" high. The close spaced holes are running up and down.

How did you rotate the job into your cutting software so it matches the table?

I must be missing something here. If the machine has the X axis as the long one then surely it's ok?

Eddie this is the first time you cut anything with this machine correct? I would run a calibration sequence as Angie suggested.

This cnc is set up for that so what i see on the PC screen cuts that way from side to side so i do not need to flip it.

Yes just working on getting it up and running it has been off for some time now..

I will do the test i need to find the test place in Mach 3.

You should see a tab at the Mach 3 screen top that says "settings". Click on this and then on the lower left side of the screen should be a button for "set turns per inch" (or something like that). Then follow the instructions.

when you move your gantry 48 inches does it move 48 inches.

Hi Eddie, The next thing you want to do is check the tram of your spindle. The tram is the equivalent to plum, true and level in a 360 degree radius. If your end mill is cutting flat then you should be fine. If you are getting a gouge on one side of the cut then your spindle should be aligned.

Have you cut a spoil board for this machine?
