DIY CNC Step Clamps Part -3

3D Printed CNC Clamp on CNC Bed from XYZprinting Da Vinci 2.0 Duo 3D Printer

 

So here we see the clamp we printed the last time on the XYZprinting Da Vinci 2.0 Duo 3D Printer sitting in the step clamp from the first part of the project and its holding a melamine board sitting again on the CNC Blocks we printed on the XYZprinting Da Vinci 2.0 Duo 3D Printer in earlier project. Note on the bed of the CNC machine we installed a single channel for installing T-Bolts.  Now this only provides two points of hold down which for most operations of this size has been enough, yet that really as not the idea as the real idea was to install jigs on bed and us this to clamp them down than the pieces to the jig.   The reason for this is the jig which we made where milled on the router to be perfectly level as this bed isn’t and most home made routers are not.  So this was an easy to over come the problem as we where milling some thing plastic on this machine in the past.  If there is a time, will post a couple pictures in the future of these bases as they do come in hand as well as speed up the job by not having to level things out all of the time.

One other note, still have not had the time to dip the clamps in the Plasti-Dip, however it is on the to-do list but there never seems to be enough time.

" target="_blank" rel="noopener noreferrer">XYZprinting Da Vinci 2.0 Duo 3D Printer bed.  Note we used the rafting option in printing as since the last firmware upgrade, XYZ Printing has reduced the bed temp from ~100 Dec-C to only 70 Deg-C so with out the “raft” we have been having problems with prints sticking to the bed without rafting (we do have a ticket open with XYZ Printing on the topic).  The other thing is since these are “clamps” the density was increased to medium at 50% fill rate, now too keep in mind these are ABS plastic, so improve the grip and reduce the pressure needed on the clamp the plan is to use Plasti-Dip (click here) to provide the clamps with additional gripping force.

 

 

DIY Video of 3D Printed CNC Step Clamp

A time lapse video of the Step Clamp project printed for our in house CNC machine.  In this video you can watch as the step take shape at about 1 frame per minutes speeding up the print process (wow would be nice if really printed this quick).

3D Printing Tip: watch how it fills in the top of the circle void in the build, this is one of the amazing aspect of 3D printing and its ability to seeming manufacture things in thin air.

Also at the end you can see the finished product on our XYZprinting Da Vinci 2.0 Duo 3D Printer setting on the heated bead. Note this is ABS plastic printed at 0.03 with 30% fill and standard speed.

DIY CNC Stand Off Blocks

DIY CNC Machine with Blocks and red dust boot.

 

Here are four DIY CNC Stand Off blocks which were printed on our shop  with a 0.02 setting and Medium (25%) fill in white ABS plastic. The idea is to provide a stand off of the material to allow a 2D cut through to fall though to the table below instead of potentially getting wound up in the cutter or using tabs.  This also protects the bed from the cutter too and the material is held in place with step clamps (there will be another post on this).  You can get an STL copy of the blocks at Tinkercad by clicking here and downloading the STL file.  Worth note is we would suggest printing these one at time rather than 4 at a time as the plastic will stay warmer as doing 4 at a times means the head with do a layer on each [block] and while it does that, the bond will be lessened and while these will not need to hold a lot of force (as they have a good sized surface area), you still want them to be semi-strong.

CNC Support Blocks

DIY3DTech-CNC Support Block for holding stock

 

In this project we will build a simple 1.5″(h) x 1.5″(w) x1.5″(d) block with a 0.5″(h) x 1.0″(w) x 1.0″(d) notch.  The idea is we print four (4) of these blocks, one for each corner of our material (a sheet good) and each corner is placed in the notch and the material is then clamped down for machining.

The idea is the material will be held about 1.0″ above the bed of the machine allowing the tool cut though without damaging the bed. The sheet good material should be of a size which allows it enough stiffness to avoid a sag, however if this is not the case.  A simple 1.0″ square cube could also be printed and slipped under the material for additional support.  However use care as the tool might strike this piece damaging it or sending it flying so always ensure safety first when working with power tools.

This file can be found on TinkerCad site under the name DIY3DTech – CNC Support Block and by clicking the prior link.  We also post more pictures of this in use soon.

3D Printed CNC Router Base – Part 2

3D printed CNC router base with laser mount and dust collection

Well the part is now printed, however not with out some headaches as it took a couple trys to get the final product out the door.  The base setting was printed .04, with 25% (medium) infill and normal shell thickness at fast speed got the job done.  In addition, we had to use a “raft” to get the large surface area to stick to the bed of the Da Vinci 2.0 Duo 3D printer as in the prior prints it kept lifting off the bed and damaging the print.

Part of this issue is likely the bed temperature being a little low as ours is set 95 deg-C and would prefer it to be at 100 or 110 deg-C to make it a little more sticky if you will and this is where the “raft” came in as with its liter weight, its sticks better and then the base has a better surface to stick to.  However in the end a portion of the print did lift up however it was late in the print cycle so it was printing the tube portion and had little affect.  As it is likely that the temperature at the edges of the bed are too cool to effectively hold a large surface area print.

Notice there are a few striations due to the rough print setting and since the part will be sanded and printed, this should not be an issue. In addition, this part was finished with our heat gun process which we will cover in a future post and likely a video too.

3D Printed CNC Router Base – Part 1

3d Printed CNC Router for Laser & Vacuum attachment

This week we are working on building a combination, laser & vacuum base for other shop 3d CNC router.  The file can be found on ThinkerCad by clicking this link. and please follow along as I will be posting more photos and videos of build and operation.  As the idea here is to build a base which adds a vacuum port as well as a laser alignment holder next to cutting motor.  While the original base was built as a 2D sketch in iDraw on the Mac (there is also an iDraw iPad version too), and then exported as an SVG (vector file) which was than imported into  Tinkercad and built up into a STL file which was then exported into the XYZ Printing slicing App for printing on the Da Vinci 2.0 Duo 3D printer.  The resulting part was then printed in ABS at .04 with 25% fill and normal shells.  One of the changes which had to be made was the use of a “raft” because large surface of the print.  See more on this in the next part of the installment project.
