I want to add a 4th axis rotary to my Foxalien xe pro and was thinking of using a BTT Kraken to facilitate this. However, I am not sure how to handle powering the spindle as I am using a 400 watt spindle and not a router. Any tips? Maybe get a smaller board of and run the 4th axis separately.

[@TheDIMONART]

It can be easily driven by DRV8825 at 2.2A, but I don't know it's good idea or not using stepstick drivers for big size volume machine...DRV8825 can handle 36V easily and 2.2A for nema23 size motors..

[@boothybuilds]

Thanks for the info

[@PiefacePete46]

Could you tell me what steps were taken to finish the nameplate, between the CNC ending at 6:15, and the final item displayed at 6:20. The rounded corner, for instance is something not done by the CNC, I'm guessing. Thanks.

[@boothybuilds]

There was small chamfer applied as a final process which did not perform very well, chamfering being a newish learning curve for me. I stopped mid process due to the part moving with the tape glue method (I was not trying to hide a blooper but thought the video too long anyway and conscious of keeping it tight). Definitely the nut behind the wheel rather than the machine at fault. I have learnt that this clamping technique is sometimes left wanting when shear forces like chamfering is applied to smaller objects. In future I may try a 2 part 2D contour with the chamfer process in between on small objects. Being a relative newbie I find chamfering a bit hit & miss. Apart from that I just gave the medal a quick wipe over with wire wool after all 3 processes (you can see some caught in the engraving in the video). The small chamfer was rounded off a little by this process. Thanks again Boothy

[@PiefacePete46]

@@boothybuilds : Appreciate the extensive reply. The finished item is very satisfying... I thought the satin finish was either chemical, or media-blasted. The wire wool has done a great job, and preserved the shine in the lettering. Completing the chamfer before the final cut sounds like a safe way to go, at the expense of a couple of extra tool changes. Tabs or leaving an 'Onion-skin' layer, like Winston Moy used to do, are other options I guess. I've got many hours of watching, but no hands-on experience to share. 😜

[@Andratos95]

This looks amazing indeed. Where can I find the plans for this? And what is approximately the cost to make it?

[@boothybuilds]

This specific upgrade I have not published yet. Both Ivan`s original design video with links & my Shiny first upgrade and printable links are above. Ivan`s original BOM costs approx £600 (inc Makita Router, belts, motors, pulleys etc). My First upgrade will add another £100 approx for the ball screws and an additional £100 for the stock aluminium & bits. But remember I have purchased three sets of steppers and other stuff in this adventure so there is some doubling up with this evolved design, belts pulleys etc. Both LDO Motors and the BTT Kraken are linked above, I estimate that may add another £200 but again some offset with the motors and other stuff. You also really need a very well equipped workshops or an existing router to cut the aluminium upgrade parts in the first place. Depending on experience & skill level it may be worth considering Ivan`s primarily 3D printed design to dip your toe in the water but also have the ability to upgrade the router, if that makes sense.

[@Andratos95]

@@boothybuilds I was thinking that I may try your design but print the aluminium parts in PLA-CF (maybe making them thicker) and then slowly try to CNC machine the aluminium pieces, so that I upgrade the machine with the machine itself

[@boothybuilds]

@@Andratos95 Should work, it would be a cost effective upgrade route too. You can always test and make larger if not working. The ball screws are the most important part IMO. The Y axis side cheeks would need to be quite thick but the extra width would be carried on the outside of the mech. On my first upgrade, the larger parts like the cheeks were fabricated, using 3D printed drill\marking jigs, then hand drilled on a bench drill. which is another alternative route. The side cheeks do not automatically need to be angled, if you could buy aluminium to size & drill also.

awesome work Mr pants,keep up the fantastic work

[@boothybuilds]

Thank you Big T

[@knobbymcfeck]

This is an absolutely awesome build, nice going! I'm curious what firmware you're using on the Kraken? I'm new to this and have a small FoxAlien machine that I want to put beefier motors on, and have been looking for a replacement board that could drive bigger motors, I had no idea about the Kraken, so thanks for showing that! But yeah, just wondering if it's Klipper or something custom you've made? Thanks for sharing.

[@boothybuilds]

I am using Marlin ATM, I do intend to move to RRF when I find a minute! Marlin works really well, but RRFs origins are in CNC and I think some stuff like zeroing & homing may be better. The Kraken is compat with RRF, just less direct examples of install on the Kraken so will need to spend some time evaluating.

[@boothybuilds]

Also Klipper does not generally play nice with CNC

[@knobbymcfeck]

@@boothybuilds My Kraken arrived yesterday, I thought I'd give RRF a go, but then I realised I should probably get the WiFI adapter that Gloomy suggest over a RPi, so another wait until that arrives. I looked at GRBLhal as well, some STM32 work has been done, but sheesh, so many things to learn and catch up on first, this is a rabbit's hornest nest...

[@boothybuilds]

@@knobbymcfeck with RRF you are in new territory and yes lots to learn, I still have not got to RRF yet on my machine yet but still on the list. Not checked Gloomy`s stuff for a while. Let me know how you get on.

[@boothybuilds]

@@knobbymcfeck Good luck, yes lots to learn, I still have not got to RRF yet but think it may be the way forward, yes lots to learn, keep me posted

[@TommyHoughton]

Nice video mate! Those Nema 23's look tanky. I'll be attempting your CoreXY Mk3 conversion on My Ender 5 for a video in July. I'm trying to build "The Fastest Ender 5" but we'll see how that goes. I'm more than looking forward to it! The work you've done, (especially with the instructions which are phenomenal) is more than awesome. Cheers, Tommy

[@boothybuilds]

Thank you & good luck

Here is a link to my discord, I tend to respond faster here, having said that, the Ender 5 MK3 conversion was a while back so would probably need to check stuff if you have any queries :discord.gg/KNEH6bm3 Here is some stuff I never got around to publishing for my Ender 5.

@@boothybuilds I appreciate it! I’ve joined, and I’ll let you know if I ever need advice. Your instructions on the build are some of the best I’ve ever seen, and the CAD assembly is there too in case I need a reference. Should be smooth sailing. You’ve done an incredible job. I intend to start finding out what parts to print and printing them around now so that they’re out of the way. I can’t wait to start the build. Thanks for the part link as well, I’ll check it out. Cheers

[@boothybuilds]

I am sure you are aware of the Mercury One build for the Ender 5 which probably as a larger community than my efforts Not saying it is any better but clearly biased :) ), start of Steve`s Build series on it here and links in his videos. kzbin.info/www/bejne/nqvHnGCDp5KlhZY Best Boothy

[@TommyHoughton]

@@boothybuilds I certainly had a good look at it, but I couldn’t justify the cost, and the chances of getting a kit sent were minimal. Your build looked easy to achieve with less time and money, especially with the documentation, so I decided it would be best to follow that instead. Aurora Tech Channel has their own Ender 5 CoreXY conversion, but as mentioned, your documentation is above all. Thanks for sharing Steve’s series, I’ll check it out shortly. Cheers

[@PiefacePete46]

My interest is desktop CNC's of about this form factor. I have just finished Binge-watching all your videos on the Shiny CNC. You do lovely work, and your attention to finishing detail is mouthwatering! I watched Ivan's video back when he released it; you have refined that design somewhat. Thanks for taking the time to share it... Liked & Subscribed... Hungry for more! 🤤 😜 👍

[@boothybuilds]

Thanks, next up will be Reprap Firmware install. To date I have not installed RRF on any of my FDM stuff so zero experience & a good challenge. Not a lot out there for the Kraken so should be interesting. I really like using Marlin but the majority of info out there is V1 Engineering based and a lot of it long in the tooth, not all, some really good stuff but I am struggling a little with current release Marlin in certain areas (mainly Z probing & homing) it recently being very different to earlier versions. I may take a lead from the Milo Millennium team RRF install. An invite below to my discord, there is no Shiny stuff on it yet but much faster to respond to queries, I am waiting out of courtesy for Ivan to allow to OK this, he has said previously that he thinks this now mine but professional design courtesy & IP is a big thing to me. discord.gg/sBu2q9dn

[@donovannewton9507]

Did you run dual steppers on the X-Axis? Can you run another pair doing that?

[@boothybuilds]

Single stepper on the X axis, dual on the Y axis. Would be difficult to add a second x axis stepper with he current configuration. X gantry would need to be enlarged considerably
