I made this mount and shared it on the facebook group its pretty robust with the original back plate on the 25mm kit.
This is for the mckm28 600w router by Mckeller, which is one I already had and didn’t fancy shelling out for another.
It has 3 parts, two of which can be printed twice to add more support at the top but honestly I don’t thing it will be necessary.
If you do use this please bump this thread so I know how many people this has helped out.

So reprinted the top rear twice and front one once so now I have two top mounts as I originally designed it to have. Through over tightening the rear bracket piece snapped. The new parts are in black pla since I ran out of the original blue. I actually ran out part way through printing the last of the four legs but managed to manually swap the filament mid print pausing my anet a8 and it worked fine. I upped the speed on the mounts to 150 which was 3 times the 50 it was at for the mckeller mount parts here and my printer appeared to cope. There were more imperfections but liveable for what it needs to do. I had a disaster though when I came to place it back into the centre gantry, the bottom bracket part snapped on the right hand side so that the right bottom rail guard only has three bearings attach now. I tried to glue it back but I think the epoxy I have doesn’t work on PLA. Will just reprint the part but really slow and max fill.
In other news I am making sure my 3Dprinter and MPCNC has a proper home in the form of a garden office. Took a couple of days off and dug a hole and poured some concrete for the foundations. Here is my dog helping dig and the result so far.

Dui, ni shuo de duiParticipant
From what I see on the pictures, you clearly have a major extrusion issue.
My guess it that your nozzle is partially clogged.
You should take it apart and clean it, hopefully it will solve your problem.
Other tip: superglue works perfect to fix broken PLA parts.April 24, 2017 at 4:26 am #32116
you may well be right on the extruder. I am just coping with it at the moment since its dialled in right for the autoleveling, I have a e3d hotend clone which I intend to swap in soon and external mosfets to allow the hotbed 24v to heat quicker. And I intend to do a Bowden extruder as well but since its mostly working I’m just making sure I finish all the parts for the mpcnc first. Will try again with super glue too. the stuff I used is good for acrylic but I think it makes the PLA weak. I might have ruined it already with my first botched rescue attempt. Will give it ago but its not a massive hardship to reprint it.
My printer really needs a bit of tlc but time and apathy when it mostly works is really self defeating.April 26, 2017 at 3:03 am #32229
tried super glue (cheap knockoff) didnt work, going to print slow tonight, i have 40mm/s and higher infill dialed in so hopefully i will have a stronger piece this time. dont really want to tear down my anet a8 printer just yet to clean it up. I have a replacement nozzle i can use maybe i should do that at the least.May 2, 2017 at 2:31 am #32546
well I reprinted the lower part of the middle assembly in black, printer calibration was way off so consequently it lifted at the back while printing and may be a bit out but the print completed and it fit together okay so its all back together again in my temporary office in the house. After that i did recalibrate my printer properly. I designed a box for my dcdc bst900 which i use to charge my electric emax scooter. That print was pretty good, no lifting and a good first layer. Will start improving the printer with the e3d hotend and external mosfets for the bed and hotend and use a 24v supply. just need to print all the required bracketry for it and maybe buy a different inductive sensor since the mounting of the cylindrical ones is easier to calibrate and fit.
I moved the concrete walls for my new external office on to its foundations, I am a couple of weekends work from having a permanent 24/7 runnable location/final resting place for the mpcnc, till then im a little less than committed in finishing it as i cant run it in anger till i have the office outside done anyway. There is a little person in the house im am not allowed to wake with my projects.
Its tempting to get the MPCNC plotting with a pen i.e. finish the electrics but too many other jobs too
Did some CAD work in fusion to work out how to use the old sectional concrete with the existing garage. There is a visible raise where the new foundation is poured so you can tell what is old and new just by looking at the step up in the wall nearer the back.
Anyway here is a teaser. tempting to print this out to help aid construction when i have a team of people to do a walkthrough of the build first.

So I have had to reprint both the ends of the middle array as both broke in the same way. The replacements were in black with the original in blue. At least there is more symetry to it and the fill was increased to help prevent it snapping again.
In other news I made the first stud walling for my office (which will house my MPCNC) The are actually the triangles for just below the roof and they have taken me 3 days to build. However the MPCNC came in handy as I was able to use it as a MPMC as in mostly printed manual control. in that i dont have the motors installed yet but clamped the x and the z axis and used it as a railed trim router on some brackets i hadnt cut perfectly. So its dirty and its not even fully assembled.
Anyway its made me really itchy to get going on it as i can see how much easier my life would be contructing things with this than with most my other tools.
Stag do abroad next week, but once im back from that I will be all about the MPCNC again.May 22, 2017 at 6:04 am #34147
That workshop is looking cool. It reminds me of Frank Howarth’s mammoth shop. You’ll have to name it, and then carve a sign for it. 🙂
I have mine in my garage, but my 2.5 yr old will sleep through it, once he’s actually out. I just get the complaint from my wife when I slam the garage door, but he sleeps through anything.June 12, 2017 at 1:40 am #35678
So i was supposed to put up the rest of my office walls last saturday, but the rain poured all morning which meant the mastic for between the panels was never going to stick. Anyway this made me go away and think about the application of 25 or so tubes of building mastic with a hand squeeze sealant gun. At the best of times its horrible getting a consistent bead with these so i decided i would be better off designing my own.
Basically it is based on the z axis in that it has a 6mm threaded rod and long nut build into some plastic printed end caps which go into some drain pipe with will hold the sealant tubes. (i had excess lying about and a template from my ramps box design already. I will couple the threaded rod to a cordless drill and use the speed setting to extrude a consistent bead onto my concrete panels. thats the plan anyway. just waiting for next weekend and a bout of sunshine.
this one i created using a sample of Element by ntopology. i have a trial 90 license but since my paternity leave is 3 months thats a nice fit. I tried printing this mesh but the results were a bit disappointing. i think the liquid/uv based 3d printers would cope much better but it was a bit of a torture test for the anet a8.
