Hi Marcel, A few years ago you gave me a lot of help when I was building my own machine, especially with the electrics. I watch all your videos and always learn from them. This new machine is gonna be a sensation. Thanks for sharing with us. Best regards, Gareth

Hi Gareth ! Thanks for sticking along for such a long time already... Good to hear you're still around :) Yes electronics is always a fun thing to think off :) so many decisions... I'm not even sure what i'll do on this machine. For now I can run it with the BF20 controller I had build (to be found on my webpage RoboCNC.nl ) I will be talking with you guys online on the controller soon I think :)

Hi Marcel, I accidentally stumbled upon your video feed and decided to drop a note. First and foremost, thumbs up on your build! I used Item's aluminum profiles in the past and think can vouch for their superb quality, finish and thought through accessories for each line of product. Thanks for sharing your sources for the build, I found it very helpful for myself! The only thing that I am still in search for is na machine shop to mill the side plates for my build. When I fist saw your router assembled I found striking resemblance with my drawings :) I also used the idea of recessing table bed in relation to Y axes in my case, but used 80X160mm profiles instead of two rows of spaced 80X80mm. Thanks again for sharing your design! Good Luck! Arthur

Only just seen this video and what a brilliant well designed and built piece of kit, I want one desperately 👍👍 I’ve 45 years of NC & CNC machine tool experience and on your point of ball screw expansion, an old trick is to put Belleville washers before the lock nut on your loose end. This helps stop the ball screw whipping/bouncing at high speeds and also lets it expand due to the compression within the Belleville washers. P.S. Can I buy your machine 🙏👍😄

Looking good, Marcel! In your new design You've corrected almost all the weakness my old machine has: -yes, this 4Nm motor will be perfect, and it doesn't stick out what is always a problem for me since I move my whole workshop a lot to different movie studios and back to mine after productions. Helpers damaged the motor two times so far... -I have 16/5 ( not sure of the pitch but something like that) spindle on the X axis, and yes, it is weak and slow. Btw my machine's envelope is 1200x2200mm, so inertia is a serious issue. Yes, I have fix bearings on both sides and caused problems for me already. -I have 30mm spindles along the Y axis, and they do wobble on high speed, and ofc reasonable acceleration is pretty hard to achieve. I wonder how you'l do this, I'm about to swap these to rack and pinions. You've done an awesome job here, so the hobby-cnc community can't be thankful enough for sharing all the plans and your experience. Keep up the good work, Marcel.

Hello Marcel, I really have to know if the power of the X axis motor is sufficient with 4.5 NM. , I have a 3nm motor and maybe it is powerful enough? Thank you
@RoboCNCnl4 жыл бұрын
I think even with the two pieces of 3Nm you will have plenty of power. It's all about how much you ask from the machine, especially in acceleration and tool engagement.

Great videos and thanks for sharing all the information If I have understood well then choosing the screw with greater pitch, 10 and not 5, it increases the speed and the acceleration but it is necessary a motor with greater torque?
@RoboCNCnl6 жыл бұрын
Increased speed and acceleration means the les torque... if the speed goes up a factor 2 the torque is divided by two.... Its up to you what size motor you choose of coarse..

Hi Marcel Nice job on the CNC. I'm building a CNC myself, I plan to do the same as you for your Y-Axis and put the ball screw on top of the gantry. Ive decided to buy a MBA15F motor mount like you and I just wanted to check the measurements you use for the ball screw fixed end machining, are they standard for FK15 ends? F = 20 mm E = 47 mm

Hi Gerard, I'm not sure about what measurements you mean... But You can check for your self since I have provided the drawings of my design on my website.
@garyg12546 жыл бұрын
Why did you put the screw on the top of the gantry instead of behind it where it could be shielded? I am asking this because I am looking to build one because every machine that I see has in my opinion a design flaw or two.

Because i want the connection to be as short as posible.. on the back it would require some sort of L shape.

Hey Marcel a quick question please sir. What is the full depth of the gantry - say from backside of 80x160 to the center of the spindle? I figure on ~ 300mm or less, the part of the table that will never see any spindle action at all :-) Right now I am at exactly 1500mm total bed length to allow for 1240 length material, but I am probably running very close. I am also going to cantilever a rotary tool across the front. Bolts on to some 0.250" plate or tube that will also square up the two sides. This steel is heavy enough, I must divide the table into three sections.

Hoi Marcel, ziet er goed uit zeg, wat me wel opvalt is de verbinding met de z-as. ik snap wel dat alle druk en torsie op de hiwin rail komt op het moment dat je freest alleen de verbinding tussen de z-as en y-as is maar op een punt verbonden, ben je niet bang dat je hierdoor vibratie's krijgt in de z-as op het moment dat je gaat frezen ?
@RoboCNCnl8 жыл бұрын
Hoi Mario, Bedankt voor het kijken en je bericht... Ik denk dat ik je vraag niet helemaal begrijp eerlijk gezegd... De vibratie, die onder andere in mijn vorige ontwerp aanwezig was, is ten gevolge van de trillingen in de front plaat van de Z as en de trillingen in de verbinding tussen de Kress motor(steun) en de Zas. Nu is de motor vlak op een montageplaat, daarna op de frontplaat, en dan nog op twee hiwin riails geplaatst. Ik zie niet zo goed hoe de Y as hier een rol in speelt. Als je bedoeld de verbinding tussen de kogelomloop moer en de Z as dan denk ik niet dat dat iets met deze trillingen te maken heeft. Er zijn 4 hiwin lagers die dergelijke zijdelingse beweging niet zouden moeten toestaan. Of begrijp ik je nu verkeerd?
@marioappel72108 жыл бұрын
Hey Marcel, bedoel op tijd 19.40 van de youtube video zie ik de ballnut bracket en vroeg me af omdat deze maar met 2 boutjes en maar op één plaats vast gebout zit op je z-as dit niet een zwak punt wordt? de verbinding lijkt me zo dun. . Snap dat de hiwin rails de krachten op vangt alleen de verbinding de' ballnut bracket' brengt alle kracht over naar de y-as lijkt mij. Misschien is dit helemaal niet zo maar zo op het eerste gezicht lijkt mij dat zo.
@RoboCNCnl8 жыл бұрын
Hi Mario, Ik waardeer het meedenken enorm hoor, dus schroom niet dergelijke zaken te zeggen. Ik zie echter niet zo goed waar de trillingen vandaan moeten komen, dat heeft denk ik weinig te maken met het type verbinding van de kogelomloopmoer naar de as. De trillingen zoek ik dan meer in de stijfheid, vandaar mijn verhaal over de hiwin lagers. Wat ik wel zou kunnen begrijpen is als je denkt dat de twee bouten kunnen breken bij te grote krachten. Dit omdat ik slechts twee bouten gebruik en op afschuifspanning belast. Nu denk ik echter dat ook daar geen probleem is. Ik gebruik twee M8 bouten met de klasse 12.9 (zeer sterke bouten!). Ik heb hier niet voor gestudeerd, maar online vind ik dat de maximale afschuifspanning per bout 450 MPa is. Los van dat je je goed kunt afvragen welk freesje die 900MPa zou kunnen verdragen kan de 4Nm stappenmotor deze kracht niet opbrengen met de huidige overbrenging. Wellicht dat er nog anderen zijn die dit lezen en er iets meer over kunnen vertellen. Maar anders gaan we gewoon emperisch vaststellen of het problemen geeft :)
