great video
Just found your channel and Subscribed. Very nice work
Hi, I’m a maker and just purchased one of these units from a lab. Where can I get the two software items please? Thanks for the video!
I got both CircuitCam as well as BoardMaster together with thd machine. At least BoardMaster is an old Win98 application with afaik no newer versions available. Maybe that lab can give you their license?
Good work but don't get your sleeve caught in the belt.
Did you ever complete the CNC conversion? I have a similar machine and was wondering what you did for the Z axis. Did you install a ball screw and brake, or just leave the existing screw in place and replace the motor?
jajjaajaj I do the same 🤣🤣
Thanks for sharing it is really very useful. I just have a hard time sourcing the materials but it's worth the build.
I think it is not as easy as it seems to make good and cheap and efficient and smart MPPT e.g. 50 +50 + 50 Amps 3 phase.
thanks for making this video , really helpfull
Very nice to look at, but a how-to would be better.
Awesome build! I'm working on CNC converting a Optimill MH 50V myself and I've read your German thread a few times (using Google Translate) for inspiration. I really like your attention to detail, your going to have a superb CNC machine when your finished.
Thanks for your comment. Is your conversion partially documented somewhere? Generally, there does not seem to be much user reports for this machine in the web when comparing to more common machines like the Optimum MB4 or it's many clones.
Hi, Wo hast du das Schaben gelernt? Irgendwelche Empfehlungen? Lg Christoph
Hallo Christoph, ich hab's noch von Richard King gelernt aber der ist inzwischen glaub im Ruhestand. Biax organisiert da jeweils einwöchige Schabekurse. Inzwischen führt Maschratur die Schabeschulungen zusammen mit Biax durch. Kontaktiere doch mal Franz (opa12) im Forum. Kann ich nur empfehlen, falls die mal wieder einen Fortgeschrittenen-Kurs machen, überlege ich mir ebenfalls teilzunehmen.
Echt genialer Umbau bis her, verfolge ihn selber auch im Forum...Aber nur zu meiner Frage, ich möchte irgendwann auch die Geometrie von einer schon Umgerüstet mh50v (mobasi) überarbeiten, allerdings bin ich mir nicht ganz sicher ob es sich lohnt einen gebrauchten Elektroschaber anzuschaffen. Denkst du, dass das Zeiterersparnis es wert ist?
Das ist natürlich am Ende eine persönliche Entscheidung. Meine Gedanken dazu: Die Preise für die Biax-Schaber sind zwar hoch, man bekommt sie aber auch gut wieder verkauft. Wenn du dir also einen zulegst und danach wieder verkaufst, sollte der Wertverlust nicht allzu hoch ausfallen. Ausserdem könnte es ja sein, dass du auf den Geschmack kommst und weitere Dinge ein. Maschinelles Schaben ist ja schon zeitaufwändig, von Hand dauert es nochmals deutlich länger. Wie magst du die Maschine? Würde mich über einen Erfahrungsaustausch via Forum freuen.
Fang das Feinschaben (Tragpunkte zählen) erst an, wenn du in der Fläche bist. Solang das Eck noch in der Luft hängt, ist erst mal Schruppen angesagt. Schruppen kann man doch auch mit so einem Biax, oder nicht?
Hallo Sepp, danke für deinen Kommentar. Ich erwähne das auch im Video, dass mir die Tragpunkte zu diesem Zeitpunkt noch recht egal sind - aus den von dir genannten Gründen. Auf einer offenen Fläche könnte man noch deutlich mehr schruppen (mehr Hub, schneller, breitere Klinge). Um sauber bis zum (ca 3mm breiten) Freistich schaben zu können, muss ich Hub/Geschwindigkeit/Klingenbreite auf das hier gezeigte Mass zurücknehmen.
has anyone built this thing? is it working? :) i am so eager trying the build...
This is a bit less manual than MY milling machine.
Yes, the mill does have a power feed on Z but in the end, the fully manual process using the quill still turned out to be superior
motorized Z ain't as manual as it could be...
very good technique
LPKF CircuitCam has the best, ie. fastest, tool path algorithms... 👍👏
@jabbalechat7910 - Hi, I’m a maker and just purchased one of these units from a lab. Where can I get the two software items?
Hi sr , I’m interested in one , please contact me ernesto199001@yahoo.es . Thank you
Neat idea!
Bad way to hold the job but okay maybe hold v block in vise or milling chuck to place on bed
Hi Maison. You're definitely right, should have used a v-block to clamp a round workpiece in a vise
You should shim the back of the shaft to prevent flex, this would allow you to take a bigger depth of cut also. I have done this same exercise on my mill before and the shimming was a god send. must faster.
Nice technique.. tedious but finally well worked
Very inventive solution. Thanks for sharing this. It’s a slow, tedious process but going slowly is one way of minimizing errors.
Hello How can I obtain the driver and install it Please help lpkf s62
We've obtained the drivers on a CD-Rom when we purchased the machine. The only issue is that it only runs on Windows XP so we still have this dedicated PC running on XP for the sole purpose of operating this machine.
Hello sir What motor you would suggest for a fully functional AUTOMATIC DIVIDING HEAD for commercial use .I would like to my my own in my workshop
This work manual?
Yes, the slots were all cut conventionally, i.e. manually. CNC conversion is still work in progress
Some photos and details of the tool can be found here: forum.zerspanungsbude.net/viewtopic.php?f=13&t=43263&start=130
Nice! What tool are you using and where can I get it? I’m about to do the same on my MAHO mh700 cnc mill.
Hi Martin. Should work even better on the Maho. If I had more space and level access I'd get one, too. The tool is home made out of a bar of C45 steel, turned to 25mm on top and around 14mm at the working end. There is a square hole through the thin part accepting a short piece of 5x5mm HSS that does the actual cutting. An M5 screw from the bottom secures the HSS. You can buy this kind of tools, mainly for use on CNC lathes and then they come with carbide inserts but otherwise not that different
Great job and This video help you to Make your PCB like a Pro in 8 steps (LCD Module NOKIA 3310) ruclips.net/video/vLauEnn1l_Y/видео.html
Gut gemacht. Sehr interessant.
why don't u use rivets?
Good video.
Nice .but is it control without any controller like as arduino or something else .
There is a PIC18 microcontroller on the board so there is no need for an arduino or the like
Hi, very interesting this board where possible buy? I need one. Tnx
How do you get those extra via holes on the pads? Is there an option in Eagle or whatever you're using to add separate via holes like that, or did you manually insert them?
I have one of these dividing heads, and would love to use it as a 4th axis on my CNC machine- but the backlash is large, and you cannot overshoot and come back with CNC. Even if you calculate for it, the side forces will move the head and cause problems.
Most indexers use a brake to lock the position. U'd want to integrate brake control
What kind of motor is suitable so that when cutting is done the dividing head will not lose its position as you the brake is applied
@@ajaypalsingh549 Stepper motors hold their position when stationary. However, the backlash in the table (several degrees) means that it cannot be relied on- it will move under load. If one could simply put stepper motors on machines and turn them into CNC devices the world would be a simpler place. Sadly, it requires zero backlash bearings and drive, which is where most of the cost is. This video is interesting, but not practical.
@@TensquaremetreworkshopI got you sir can we use closed loop stepper with brake for accurate and it will not move under load what would you say ?
@@ajaypalsingh549 You can lock the stepper motor, but the backlash in the gearing means the table will still move. That is why there is a lock on the table- the handle you see on the left of the table. You adjust the position and then lock the table before machining starts. CNC requires a drive that has zero backlash, not possible with a worm drive. It needs a re-circulating ball system or similar. If all you had to do was add stepper motors, CNC would be simple.
Hello can you tell me please where can I buy these small drill bits and end mills? What is the correct name of that tools?
You can find them on the LPKF web store: www.lpkf.biz/108-werkzeuge It's in German. I don't know, if there is one also in English.
Jesus, You can find them here: www.edasim.com
applause (iyour blog brought me here)
Please I have questions about your mppt can you please give me your mail address please
PCB is looking so good . nice placed components and
Great job!
Thank you
Nice - I'm thinking I need to do something similar - how did you size the stepper motor?
I primarily looked at similar projects on the web and checked out what size of steppers they used for similarly sized dividing heads. Besides that, I had about a feeling of how much it takes to operate the thing by hand, just as a sanity check. One thing to bear in mind: Steppers have a lot of torque at low speeds, and that's what they advertise. Even at moderate speeds, say 500 RPM, only a fraction of that is left...
Top ! Ist da noch eine Riemenabdeckung geplant ?
Wie die genau aussehen soll weiss ich noch nicht. Die Pendenz ist aber registriert...
Good luck, Lukas!
Thanks everyone.
Good luck
Good luck, Lukas. :)
You are very welcome!
It is so wonderful to see the boards being made! I have fallen behind on my project and need to start it back up..
