how do you test the battery and get the graph (in the software)? i dont have any info on this procedure and need it for work related things. this would be very helpful thanks in advanced

Soo cool. Any update on this in action ?

The battery's are fake

G'day, I've just ordered one of these Tenma/Korad loads. Couple of points. I would have used 4 wire mode to measure the real battery voltage as the "only 10mOhms" in one lead gives you 20mOhms between the 2 and 400mV drop at 20A so that will impact any calculations you are using that involve voltage. You discharged those poor cells way below the accepted / recommended limits of ~2.7-3.0V so I guess your capacity test will not really reflect what you would get in a real world application as you should not be abusing the cells like that! With the amount of heating you are seeing (45C at 2.8v @ 5A) it is clear they are not designed for long high discharge cycles and you may encounter thermal runaway if you used them in such an application. Cheers. -- Edit just realised this video is old...

Great project. Thanks for sharing. What software do you suggest?

this project died ? or there is a machine done with this head ?

Did you made any progres with this project or any one tried this on real machine ? As nema17 isnt a strong mottor

You could always make the gripper using a smaller stepper motor OR use pneumatics.

Hi May I ask why you did not use the battery test setting ?

What is the length of the belt? It's not in the drawing.

Great video. Thanks for review!

where can we get the files (cad or stl) for this robot arm?

hi rainer, have you finish your 5 axis project.. look very interesting to build this too Gruss Jürgen Raschke

There’s more UHMM… AHMM than electrons, here

Reiner were you able to get the LAN control working? I can't seem to find any instructions for that 🤦‍♂

Did you finish it?

Dear Reiner, I came across your interesting video because I'm looking for an electronic load. I'm oriented to buy the kel103 vs the ET5410A+ as the price difference in Europe is not very high. The last one seems to have more features like CC+CV or CR+CV LED and so on but the Korad is more accurate and robust. Do you know if the Kel103 can have the same features programming it with python? Thank you

Your measurement of the voltage accuracy (around 8:30 ) is flawed. Your test leads are pretty thin + travel through 2 connectors. If you assume that the KWR103 and your voltmeter are 100% accurate, you get a resistance of 50 mOhm for the connection. According to Ohms Law, this resistance is the reason for your lower measured voltage at 1 Amp (-0,05 V), 5 Amp (-0,25 V) and 15 Amp (-0,75 V)

Im curious about why you named this project BridgeBoy. Brandon Sanderson fan?

For all who are interested in this nice peace of psu: do not compare apples with oranges. The (left) KA3005P/6003P is a linear one with core transformer and linear regulation, whereas the shown KWR is a switching psu with all benefits and disadvantages. If you are about charging batteries, consider a switching psu because of its way better efficiency. Doing some repairs in analogue or digital circuits I would always recommend a linear psu as Reiner does. Finally, it's better to have two different for differenct use cases instead of a one who should fit all. If you do not need >30V, have a look on the 102, it delivers 30A up to 10V (from 15A@20V to 10A@30V they're both equal). jm2c.

I spent a few hours to reverse-engineering the video and F360-models to make the project more "Open-Source", so if someone willing: V-axis bearing is "6009-zz (5972K271)", U-axis bearing is "6210-2RS (5972K366)", The pulley are "1428N420_T5 SERIES TIMING BELT PULLEY" The U-belt is MEGADYNE MPW2 T5 400 3017, the V-axis belt I can't find, the video not clear about it same as at the 3D model... Hope I helped you a little 😆 Best regards, Linda 😇

Im torn between the KWR103 and 6005P. Which one is better? (I need it to drive LEDs with 42V and debug power circuits in laptops/as a psu for notebooks) Would love to hear from you! ❤

What happened with this project?

pls show use of cr mode

Hi, I assume the script you wrote is in Python? I assume I copy and paste the file into notepad?

This power supply is driving me crazy...just using it for 28vdc charging of batteries. The dislpay jumps all over the place but when measured with a DVM the voltage is stable. Can't figure out the settings to get the display to reflect the output. Any ideas?

Wow Awesome , This is cool , looking forward to add this to my cnc machine...

I like your creative design for 5-axis milling head, but I am not a big fan of timing belts. They can be very precise solution, but it won't handle any force in material. Try using PLANETARY REDUCTOR insted of timing belts.

Hello Reiner, my first bench PSU will be this Korad KWR103 or the famous Korad KA3005P. Which do you recommend, which is better in your opinion?

this is a moveo copy

Hello Reiner, did you shared somewhere V1 or V2 files? currently planning to build myself one and checking out different designs to combine fot mine.

Just downloaded model, those bearings will have running clearance?

Hi, I'd use several RND KEL102 (same looking) load device with aligned load stepping. There is a "trigger" connector on the back, but not a single word about it in the datasheet. Do you know how to use trigger input? Logic level, or opencollector/drain to short to trigger? How fast load switching can be (I'd load LDO power supplies)? Any info on that would be appreciated:))

2:32 P= U x I Power supply Korad KWR103 =(60V/15A), 300W ;-) 60vx15a=900 But We have 300W et voilà it's a Swing to one side! You can sew 5 and 10 hats from one skin, and the essence is not in the hats, but in the size. I prefer one Well in size!

If anyone has built this I'd be interested in having a discussion or looking for a good forum to chat online. I've downloaded the CAD files but it would be good to speak with others and get a sense of any updates/gotchas since the 2018 release of this video. Reiner's info has not been readily available online but it seems that he may be on to newer projects at this time. Thanks.

très bien réaliser mais je doute sur la solidité en usinage je travaille aussi sur mon projet de 5 Emme axe mais en aluminium

This is amazing! This is really high quality work! Are you still developing this? I don't mean to make you feel any pressure or anything... I am just really excited! I can't wait to hear from you!

Amesome design Reiner! any updates so far on this?

I modified these files as you suggested. Printed in PETG, I found straight 1.78A rms NEMA 17's to skip steps, so went with a 5:1 planetary. Using Dynomotion Klfop board and software to handle the kinematics. Just test cuts so far in foam but seems to be promising. Once roadworthy will machine a foam main body and do lost -foam casting. My belts seem a hair loose for some reason so added some ultra "custom" tensions. Maybe a redesign to build in tensioners? idk, anyway thanks again for getting the design out there!

Reiner, Do you perhaps know when there will be more stock of the SlushEngine: Model D Stepper Motor Driver. I'd like to buy one. Is it possible to have a Stepper Motor Driver that connects to USB instead of the GPIOs?

very nice , i like your job ,any chance to share drawing pls .. ?

Nice video ,very cool project,im building my CNC combo using Rack & Pinion drive .. :) for sure i want to build head like yours but of Alu. Thanks for file ..!! ​ua-cam.com/channels/NmOINTaJ1jUHMGe7ql2bQg.html
