If you can spring for the spindle, I would go that route personally. Mount is the most rigid and sits closest to the center of the gantry. Although for wood/plastics/foam only, might not need the extra rigidity.
The ID of the makita and 65mm spindle mounts are 65mm for drop in stuff, just need to model a 65mm tube/cylinder then put the pen mounting stuff in it. Just make sure the tip of the pen can reach down to your table (3.5" distance from the bottom of the spindle holder to the table at Z min).
ok. Thanks. Iāll give that a try and thanks for the advice of the spindle. I might be getting into this for the wrong reasons. Either way, Iām going to learn and have fun.
Sorry to ask another question. I want to make sure I source the right steel tubing. Would 3/4" EMT conduit work for the 1" OD steel tubing (I think the real OD for this would be 0.922") and the same for 1" EMT conduit (real OD would be 1.163") vs. the 1.25" OD steel tubing? If not, what was your source? I donāt really want to mess this part up, nor any other ;-).
EMT is not sized right for the mechanics on it, nor is it as stout as the steel tubing. I was personally able to go to my local welding/machine/steel supply shop to pick up the material. If you donāt have a local place to get it places like McMaster.com, Onlinemetals.com, and midweststeelsupply.com can ship the material to you if you are in the US.
It should be around $100-$120 for all the tubing for a 2ft by 2ft machine right now, steel pricing is still a little on the silly side right now. If I had to special order material I would do midweststeelsupply since their pricing is right in line with my local shops.
The tubes for me to build a full sheet lowrider was $95, but that was years ago.
If you have a tractor supply, or rural king close by, they sometimes sell DOM steel tube in the welding section. Itās not stainless, but a light coat of paste wax will keep it from rusting.
The only option is steel tubing imo. EMT is dimensionally incorrect, you would wind up spending around $150~$200 on the one piece of 1.25" stainless tubing if you went that route, the 1" SS tubing is almost twice the cost of regular steel tubing, and CF is not suitable for a bearing surface, it could be epoxied to the ID of the steel tubing to increase stiffness but it really isnāt needed.
That is a good start to a list of potential places to get the tubing. It is the one thing that I have no clue on how available it is to other people. I have 2 welding/machine shops within 2 miles of me that I can swing in and get material from cut to length, I basically only have to order it if I need a specific size or a specific material that they donāt have on hand. I am absolutely on board with putting a good list of places to get the tubing from that people have had good experiences with.
Iāve started printing the Brutusā¦ Still havenāt finished the LR3, but I had to sacrifice two of the steppers I ordered for another project so I guess Iāll have to put in a second V1 order for two extra motors and parts for the Brutusā¦
Do you control the VFD with a 10v control signal or just adjust on the VFD itself?
Does the misting system cause the timber to swell?
I just manually control my vfd with a remote switch (fwd/off/rev) and the trim pot on the vfd for speed adjustment.
So far the mist hasenāt caused swelling on the MDF base I have the fixture plate and vises mounted to, want to make a new table for it so I havenāt bothered coating it with anything.
Nuts and Bolts from BoltandNut. This is awesome as you can order the exact number. Just watch the price points listed, as buying an extra one can drop the total price.
Thereās also a free, or low cost, option. When the tarp gives up people give the frame away or sell it for nominal value. Iāve picked up a couple of these and salvaged a load of 4ā lengths of 1" and 1Ā¼" OD tubes for my builds.
Just to put my .02c in on the matter of steel tubing, I was able to get everything in 11ga (.125 wall) 304 stainless from cormark metals for right around $220. A bit pricy, but I have a lot of humidity to combat.
This is also sized for a 2ft x 4ft (with a smidge of extra) cutting space. I havenāt finished printing and assembling, but all of the parts are pouring in and half assembled on my desk as things come off the bed. All in Iām at about $550 without PLA+ cost, wiring and controller. The power supply I have is a 300w 24v supply I ripped from a robotic vending machine at work for free.
and have fun.
