Great series of videos Ade, I have learnt a lot. A while back you mentioned providing a list of all the parts you used. Could you still do this? It would save the rest us from having to re-invent the wheel. Many thanks.
Hi Ade Thanks for all the interesting videos. I am building a feed in X for my milling machine. I have bought a pulse generator like you use, with buttons on/off, forward/reverse and a potentiometer for speed. I have intended to mount a limit switch on the table. how do I connect them to the pulse generator. do you have a wiring diagram for it? Thanks in advance, Mike
My friend that restores old MG's always says, "Foster's is direct substitute for motor oil in old British motorcars." Nice video! You might want the switch to have a metal activator that is bent to look like a paper hat so it doesn't get hung up.
Hi Ade, An enjoyable video... If I've understood correctly your limit switches will work a like a surface grinder (I am assuming they all work like the one I'm think of - not to smart there Paul). Have a good week. Paul,,
A brilliant addition - I've got the same mill and would like to add this. I couldn't find the NEMA parts list in any of the video descriptions (six parts?) - if you could add them that would be great!
Cracking job Ade, that motor sounds sweet as a nut. For a minute there, I thought Ahhh, a tin of Fosters, that makes me look slightly better, then you said it was for comedic effect........ Oh I feel bad now! Think I am going to have to adjust my camera angles in future lol. Keep it up mate, all good stuff and very interesting. Cheers, Jon
Hello, i think i would like to make a similar solution for my mill, but one question, will manual operation still be possible with the handwheel, or vill it be too heavy since one also will have to turn the steppermotor, because i suppose there are no copling to disengage the stepper motor for manual operation, right?
Hi, Love your build. Did i miss something or can you still feed the X manually? I understand that if a stepper is turned manually it can backfeed voltage to the controller.
Hi, I am fascinated with your work,you’re excellent teacher. I have questions abut the lathe ⚙️ how you know witch is witch I min the size. Will you please explain to me.thanks
Don't like to be negative, mate, but if it were me, I would have separate conduits for the 24V and the 230V, separate, and suitable plugs, and the 230V would be picked up after the emergency stop and the chuck guard. Then, the table motor is easy to stop in an emergency, and gets shut down when the mill is powered off...
You will wonder how you managed without the power feed once you get used to it, now for the Z axis to save having to wind that heavy head up and down. I always remember a question about fosters, someone asked crocadile dundee on his visit to London " can you tell me the way to cockfosters" to which he answered " sure, drink it warm mate"
Hi Ade Really like the finished drive. Would it be possible to provide a wiring diagram, motor driver model and settings please? I hesitate to suggest a comment, but would it have been possible to use a different speed controller pot, with a nice turned aluminium knob and to have it mounted on the switch panel? Oh and have you consider using Hall effect and little neodymium magnets for the limit switches, they would stick anywhere. Many thanks as usual Cheers Noel
Motor defined seems to NEMA series. Likely 23. You can buy them and controllers from multiple places like stepperonline com is one I've used if I recall correctly. Could've been steppers. Not sure but Google it
Hi Jothain. Thanks for the reply, I’ve added a drive on my mill using a 23 etc. A year ago and have been waiting to see what Ade would do. As usual he has made a much better job than me. I was just asking about the equipment he used, the settings, and a wiring diagram. My setup is OK, but if I try to start it at a fast setting, it stalls/buzzes. I understand how steppers work and know what’s happening but am wondering if I have the dip switches set at optimum. Thanks Noel
@@Jestey6 You gotta check/ confirm following, but if I recall correctly and you use more steps per revolution, you'll also lose quite much torque. So basically more steps,more accuracy,less steps,less accurate but more torque. I've fiddled around a bit with 3d printers small steppers. I'd think was 400 steps per revolution is more than sufficient for your usage as I think you have belt drive with pulleys likely in your setup? Meaning that it's even geared and you'll have essentially more than that 400 steps per revolution at actual driven shaft. I hope this makes any sense, English isn't my native language.
jothain I would never have guessed that English wasn’t your first language, your English is a lot better than the majority of people here. Thanks for the information I will check it out. When I did my mill, a year ago, I was not conversant with Arduino, not that I ended using one, stepper drivers and motors. So I removed the 2 switches, not easy when they’ve used unleaded solder, when the holes were clear I soldered in a number of wires. Ade has managed to achieve this with only a couple. I know he’s very busy, but I’m hoping he will respond with a wiring diagram and the other info. Many thanks Noel
Nice work. That is not a "transformer". It's a swiched power supply. Anyway, it discipates heating. Well done keeping an eye on the temperature inside the box. Working on an electrical power feed for the lathe, being much more simple. Testing is near to take place. If it works, You wil be horrified...
thanks Ade, the power feed is a great job, very quiet. You've left us wondering what the next project is, more on the mill or is that mini lathe about to receive attention? Best wishes, Stephen.
