I recently got my gen2 elite journeyman, which I have on a QCW rolling folding stand. I am generating carves with vectric aspire, and using the bits&bits 1/4" downcut with the default vectric settings, taking 1/4" to 3/8" per pass. On straight runs and curved corners, everything is fine. When I am cutting out small parts that have a lot of back and forth, things wobble a lot, and I think I’m seeing significant cutting errors (like 1/16" over/under shooting paths) due to the wobble. I have tightened every bolt with a drill on a clutch setting to ensure uniform torque, which is about as tight as I can go without risking stripping out the socket heads.
I have many very, very long 3D carves to produce. What can/should I do to address this wobbling? Should I drill holes and add additional cross bracing, or are there other approaches I could try?
I just was looking at the settings, and it seems that my redline controller defaulted to 70866.142 in/min^2 acceleration for all axes. I dropped this to 30k on the X and Y axes, and it seems to wobble noticeably less. Is this also reasonable to do?
Absolutely nothing wrong with cutting your acceleration values.
There’s what possible with the machine on an ideally rigid setup like HartailSr’s (have you seen the automatic lift of his rotary, that’s pretty sweet too!) and then there’s what’s realistic based on your personal setup.
I built a table for my 3D printers - half lap 4x4 with 2x6 stringers. I have a pair of H2D’s and even in ludricrous mode they table doesn’t wiggle.
Did I have to use my forklift to get the table in the double sliding door on the back of my house…maybe - but the house is also a slab, so nothing moves…
I plan on making the same style table for the CNC - my current table is going to be repurposed to a table saw outfeed table. I want to do 6x6, but I am afraid my forklift won’t be able to move it - so sticking with 4x4.
My problem is that I absolutely need to be able to move the CNC out of the way in my shop. Sometimes I need to reconfigure to rip 12’ boards, or to set up a joint-plane-table saw-drum sander pipeline for material prep. I had hoped to do that with the rolling folding stand, but I might end up needing to build something custom like you guys have. I already specialty tables with scissor jacks and locking flip mechanisms for my planer, drill press, miter saw, radial arm saw, and disk sander, so eventually I’ll come for the CNC lol.
So when the table is down it is 100% solid and then when it needs to move, I install the wheels and move it. With the QCW and rolling table, don’t you have to make it vertical before you can roll it - that means clearing everything off etc
Mine will be at the height the table could be used as infeed or outfeed for anything in my shop - everything is set at 875mm - so pretty much any table or rolling anythign can be made into infeed or outfeed or material transport as needed
