My max Z height is very low. What am I doing wrong?

Post by kristenanne77 » Sat Jun 27, 2015 1:36 pm

After installing the dewalt 611 and raising it to the highest point (the springs are squished closed), the distance between the collet nut and the stock Shapeoko 3 wasteboard/supportboard is less than 3 inches. This does not include adding a sacrificial wasteboard above this, adding a milling bit, and an actual piece to cut. This will give me less than an inch to work with.
I have attached a pic of it at its highest point above stock wasteboard with no bit installed. Between waiting for 3 different orders of missing parts and a month with this thing sitting on the kitchen table, i think i forgot forgot what I am doing.
Can anyone point to some clues to fix this? .... :?: My brain is fried...

Are you using the upper set of mounting holes?

It looks like you can raise the router up a little in the bracket. Mine is all the way up to the spindle lock button.

Taking into account everything I've previously said - there is 100mm (~4") of total z-axis travel. So... depending on which set of mounting holes you use, how far into the mount you put the DW611, and what size bit you're using, and what clamps you have, will ultimately determine how big of a piece of material you can cut in the machine.
The other thing to consider is the distance between the wasteboard and the bottom of the X-axis plate - which, off the top of my head, I believe is about 95mm.

I didn't raise the dewalt any higher because then the holding clamp would then be pressing against the yellow button i need for changing bits.
BUT
I realized i could raise the mount up an inch. Big help!

Thanks

This wont help with your Z height being any higher, but I did notice you have your Aluminum Standoffs in the wrong mounting holes. I think their purpose is to prevent the Z carriage from traveling too high and possibly damaging the motors and springs. They should be mounted in the set of holes below the motor.

I was having issues with the X axis V wheel bolts interfering with the Z axis springs slightly, until I realized I'd forgotten to put the extra set of washers on those wheel bolts. :?

Fortunately, I was able to use those same washers to push the spring out another millimeter or two, which also seemed to work, and didn't involve disassembling the entire X axis carriage.

Could be useful info if anyone else makes the same mistake.
