I'm planning to do this too, including the bit at the end about setting start/end points so I can do multiple passes effortlessly. I don't have a way to cut threads at all yet, but my spindle is made out of a hoverboard motor so once I add a leadscrew motor I can do coordinated motion easily. The rapid movement back to start will also do coordinated motion, "unscrewing" as it goes so I don't have to retract the tool all the way out of the thread for each pass. Having a closed-loop spindle is awesome, by the way. You can set the torque so it will stall easily if anything goes wrong, but will maintain the commanded speed right up until that limit. Much safer than using massive torque to prevent slowdown under load.

[@9darkspells]

8:57 if im being completely honest, the moment you had given the pulse count of the encoder and the expected RPM range, I went to my trusty napkin and tried to scribble down order-of-magnitude estimates for how many clock cycles you would expect to have between each interrupt. Given that the pulse count I estimated gave around 200 clock cycles between each interrupt, I honestly had thought the tiny would have been enough, and I'd probably have been just as confused as you as to why it didn't. Though admittedly, with 200 clock cycles there would definitely not have been enough cycles to get all of the pulse counting and pulse sending done while still having cycles left over for writing debug information to the serial line.

[@username34159265]

I just heard 2000 PPR and 2500 RPM and thought "that needs to be done in hardware". STM32 blue pill boards, Teensy 3.x or 4.x, RP2040, and most everything just slightly better than a base 8-bit MCU can do quadrature counting in hardware. If the servo loop rate were only at a couple kHz, that would be fine. But yeah, quadrature with a decent encoder means you either need to count each cycle in your ISR assembly code, handle it in hardware, or punt to something with a stupid fast clock.

[@jasongaunt]

He did say he was doing a lot of Serial print's, those are quite expensive in themselves :D

This is almost exactly the same setup we have at Zaber for cutting plastic worm gears. A high resolution rotary encoder on the low speed side feeds a teensy which converts it according to the desired gear ratio and sends step and dir pulses to the cutter motor. It works well at constant speeds but doesn’t handle accelerations well because the latency of the conversion process turns into a position lag.

[@NoEngineerHere]

I ran into the same issue, I figured it's not too much of an issue as long as the following error is somewhat constant, ie don't change spindle speeds during a threading op 😅 Am planning on swapping the spindle motor over to a servo at some point, then I can just send pulses to the spindle and lead screw motor simultaneously, allowing for fully synchronised motion.

[@Rudmin]

I didn’t know about the line algorithm or consider how computer graphics could relate to gearing. I think the way my code works is it takes the current encoder position minus the previous encoder position plus a carryover amount and multiplies that by a ratio to get an integer number of pulses and a floating point remainder that carries over to the next cycle. It’s definitely not speed optimized but it’s quite robust to accumulating errors.

[@spicybaguette7706]

9:43 The driver knows where the motor is at all times. It knows this because it knows where it isn't. By subtracting where it is from where it isn't, or where it isn't from where it is - whichever one is greater - it obtains a difference or deviation. The driver uses deviations to drive the motor from a rotation that it is to a rotation that it isn't, and arriving at a rotation where it wasn't, it now is. Consequently, the rotation where it is, is now the rotation that it wasn't, and it follows that the rotation that it was, is now the rotation that it isn't. In the event that the rotation that it is in is not the rotation that it wasn't, the system has acquired a variation, the variation being the difference between where the motor is, and where it wasn't. If variation is considered to be a significant factor, it too may be corrected by the driver. However, the driver must also know where the motor was. The closed-loop stepper motor scenario works as follows. Because a variation has modified some of the information the driver has obtained, it is not sure just in which rotation it is. However, it is sure where it isn't, within reason, and it knows where it was. It now subtracts where it should be from where it wasn't, or vice-versa, and by differentiating this from the algebraic sum of where it shouldn't be, and where it was, it is able to obtain the deviation and its variation, which is called error.

[@LordSaliss]

Love this project. I actually did it myself as well but with a PLC instead. I used a Productivity 1000 with HSC module and an PS-AMC4. I replaced the main AC motor for the spindle with a servo as well, so the leadscrew has its own servo (1kw) and spindle has one (1.5kw), then used the Gear Drivetrain instruction to sync them and allow me to modify the ratio between them via software whenever I want. I am putting a CM5 HMI on as well with a numerical entry box to let me type in the feed pitch/threading pitch I want the PLC to calculate for me and enter the right drivetrain numbers 😁 Costs WAYYYY more than the equipment you used, but I was familiar with PLCs from my job and find them very easy to use, and will allow me to expand the project more in the future. I probably should have started with more arduino type hardware but I didnt want to try and learn the C software coding and I was worried about troubleshooting something I didnt understand well yet. This will also let me add in DRO type linear encoders into the PLC in the future and integrate all the XY position feedback into the PLC as well to start letting the lathe do some automation as well sort of like a seni-CNC. its a fun project Anyway, very excited to see you do this as I thought I was the only one so crazy. haha.

[@Maxjoker98]

Bresenham's line algorithm is actually fairly straight forward. I don't claim to understand all the derivation, but in the end, it's just: calculate step sizes, keep track of "rounding errors"(difference between integer pixel coordinates and actual position). Coordinates are always integers, and lines are always "connected" to themselves, so one axis is just an increment-by-one every step, the other axis has a step value, and if that step value plus the error is bigger than the current coordinate, increment the current coordinate and note the new error value. You need to make sure the line is oriented correctly, but that is simple as well.

I made this worked on a regular arduino 16 MHz by reducing the encoder mechanically to 400 pulses per revolution (instead of 2000) which gave me around 1000 clock cycles per tick to output pulses to the stepper. Plenty if you're careful!

[@IsZomg]

I also implemented all the features you mentioned at the end - a shoulder stop, automatic re-synch with the spindle to start the threading, and I threw in multi-start threading while I was at it.

[@robertsneddon731]

Screw-cutting is usually done at quite low spindle speeds so the pulse rate out of the encoder should be manageable. A better solution would be to use an absolute encoder (Gray encoder) rather than a pulse encoder since it doesn't drop pulses due to interference or slow processing and it will recover errors on the next step. Absolute encoders cost a bit more than pulse encoders though and need specialist interface circuitry. I'd also separate the encoder and motor controller system from the user interface system to reduce the chances of button interrupts and display refreshes getting in the way of the spindle/leadscrew timing.

I recently went through some what of a similar journey. I did get a nano to work-ish, by using a lower steps/rev encoder because the resolution doesn't really need to be that high. however those things are super limited on memory and they start to behave very strangly when you approach 80-90% memory use. my current version is running on an esp32. definitely a great upgrade for a small lathe. I've done all those automatic start/stop features also. at some point the hassle becomes the user interface to input the details of what you want it to do. :-)

LOL's. I have been working the bresenham algorithm on my lathe project. Congratulations!

Look up tinned stripboard. Ideal for prototypes and very versatile. Use the stuff all the time!

That was an super entertaining delivery for that video... Thanks!!!

As a former Machinist/ Mechanical Fitter/Engineer I have to say The time warped former Mc Donalds Mascot Mayor Mc Cheese was definitely a highlight of this video. Nice One...

I love everything about this, especially the missile navigation reference.

[@BornToBeCrimson]

Honestly a cool idea. Hopefully you can say it's not a deathtrap in the making and would share with those of us who would like to build our own electric gearbox for their lathe.

[@FlintStone-c3s]

You can use a belt reduction drive to get more power from the stepper.

[@ciCCapROSTi]

Hah, using Bresenham for that actually makes a lot of sense. This is the third use I found for it that is NOT drawing a line, but more generally step through a space that is partitioned.

[@LordPhobos6502]

Floating points are bad... because they introduce rounding errors you can't get rid of, which means each pass of your thread cutting will be slightly off from your last pass, and because they take a lot longer for that poor little chip to calculate, meaning it might not keep up with your spindle speed. integers ftw 🤟 (long long integers if you can 😎)

[@slarti42uk]

I have almost all the parts for this sat in a box just waiting for the day I finally get round to fitting it. Until then, the change gears need another... ...change 😭

[@jttech44]

Here's a hint, color code all your gears, and take a picture of them every time they get changed. Save that along with what that configuration was, that way, if you need it again, you can just search it up and know exactly what to do.

Soooo sick but I would have loved to see the final thing! Interface, keys, display and all 😮😅
