I have the c-beam machine and when jogging the y axis to reach the bottom of the spoil board, the machine physically stops with 35mm before the bottom of the spoil board. On the rear there is about 8mm before it touches anything physically. What could the problem be?
Soft limits are disabled, I do have limit switches installed checked and do have limit switches on one side of each axis (idk if installed correct)
Check the Serial log for clues when it stops (like false hard limits triggers) and listen to the machine itself for any noises like it's jamming.
It does sound like its jamming, but I don’t see anything in its way that would make it jam, either way there is only 8mm of travel that I can see and 35mm of space it needs to move to get to the bottom of the spoil board.
I found a screw from the bottom holding on the spoil board that was sticking down and I believe it was contacting the collar. I’m taking it out and fixing that now.
Good catch, getting in there poking/looking/moving/touching for inspection is always the best way to find what's getting stuck
So, finally got back on this and after fixing that. It’s still not going to the bottom of the board. It’s about half an inch away from the edge. Do I just move the rail to make it work?
Puzzled by the terminology here. When you say bottom of the spoil board, do you mean the front of the machine? In any case, can you upload a video of the problem?
I'm 1 1/4" from the front on the y axis. It reaches to the rear with 1/4" past the rear on the y axis. I get full travel on x axis.
Is there a chance the spoil board is both too large, and not centered? How large did you make yours? From the product page: Travel (Work Area) X Axis 13.5" (350mm) / Y Axis 11" (280mm) / Z Axis 3.5" (~85mm)
I just looked at the Cbeam video, and at about 1:47, the demonstration cut shows the endmill not reaching all the way to the front when the Y is all the way back. I do not have this machine so I could not tell you for sure that this is the case for the kit's final assembly. If it were me - because I have a 1 inch surfacing endmill, I would make it so when the Y was all the way forward and all the way back, the spoil board would be 1/2" oversized each direction. That way when it is surfaced, all areas could be reached and you would have 1/2" on both sides for clamping or using screws to hold the material in place.
I went back and looked, it says 12"x12" so I figured it would reach to the 4 corners. I see now that's not the case. So, like you said. I'll just use it as a gap. I just wanted to make sure I wasn't doing anything wrong before I continue. I have the probe which looks like you put on the front corner. The end won't reach that far so I'm going to look into that next.
Probe hooks to your stock not the spoilboard. Spoilboard is larger than working envelope to provide space for clamping solutions on some jobs. Stock must fit inside working envelope with sufficient clearance for tool moves as well.
