@@Dwayanu17 thank you. The clips were made from split pins aka cotter pins. You can get boxes of assorted sizes from Amazon they are useful for different sized work stainless steel are best. You can also use titanium solder clips available from places such as Cooksongold. These are flat strips that can be bent to shape, they can also be cut with a piercing saw. The benefit of titanium is that solder does not stick to it but they are more expensive and I'm cheap 😉

Hi Duncan, I have followed this project avidly all the way through, and have now made and/or purchased all the necessary parts etc, but seem to be stuck on the wiring of it all. I have it all made and wired up to where one has to wire in the M Pedal. Like you, I have removed all the 'Gubbins' inside the pedal that are un-needed - and have been left with 3 wires on the original cable that came with the M Pedal - One Red, one Black and one twisted together shielding wire (White). I am now testing my installation (before trying to add the M Pedal) and I am only getting approximately one cycle per second activation of the solenoid, and I can't seem to get any variation of the frequency of the strikes at all. Changing the settings on the speed controller makes no difference at all to the strike rate? I have no real doubts that there are any problems with my wiring up of the parts - have you any ideas as to why I can't seem to get past this problem? I dont want to make things any worse by trying to add the M Pedal (and maybe damaging the UNO in the process). I need to know which wires on the M Pedal connect where on the UNO - your video seems to use various coloured wires to connect this - my potentiometer in the M Pedal is wired (as you recommend) with the Red wire towards the top of the pedal, and the Black wire towards the bottom of the pedal. The White wire (Shielding Connection?) is connected to the centre pin of the potentiometer. I feel so close to getting this sorted out and I dont want to ruin it all now for the sake of asking for a little help. Your system really has great potential, but I'm just a novice at all of this. It seems that, like many others, I'm desparate to graduate from the noisy Pneumatic graver with compressor and bits of silicon tubing etc: to something far more reliable and convenient - I hope you can help me out a little. Kudos to you for a great design, I am just so keen to get my version up and running - and I can then get on with the thousands of necessary hours learning how to engrave properly! Regards Richard
@alastairduncan4702
@alastairduncan4702 6 месяцев назад
The speed controller is only a speed controller for a motor. It is a PWM controller which controls the power to a motor which controls the speed. With the super ez graver this controls the power for each strike not the strike rate. The foot pedal not attached to the speed controller, controls the strike rate. Have you looked at the documentation on GitHub?

@@alastairduncan4702 Yes, looked at all of it - even have a lot of your videos related to to the Super EZ graver saved as well! I also have all the files backed up (except the latest handpiece that is - trying out the basics first!) If I read it correctly, I think you're saying its because I have not yet wired in the M Pedal yet, and it will work properly when I do? Hence my question about the M Pedal wiring, I just want to know I'm connecting the right wires to the right pins on the UNO i.e. Red to ? Pin on UNO, Black to Pin ? on UNO and Shield Cable to ? Pin on UNO. Having looked through the video yet again, and I still can't work out the which colour of the wire on the M Pedal goes to which pin on the UNO, maybe I'm missing something - quite possible as I'm going to be 83 later this year and not used to having so much time on my hands? This is going to be my retirement hobby - hopefully! Must say I'm quite impressed at the force that this small solenoid can produce - think it will be a very worthy replacement for my old compressor setup. Thanks for your very prompt reply, much appreciated Regards, Richard

I can't help thinking that these two wires should be reversed? Not tried it yet though, too scared of letting the magic smoke out of the UNO!!!)

@@theOdin-odin at least 2 layers of enamel. Once you have ground the enamel smooth you may find some low spots which will need to be filled. You can cut the walls very thin but there are risks, you have to be much more careful. The walls of the cells don't have to be the same thickness all of the way down. Try having the base thicker. You can always thin it down afterwards if you are not happy. Try it on some copper first until you are comfortable with the technique.

When a solenoid gets hot the resistance in the coil reduces. This will reduce the power that flows through it and hence the magnetic force it can produce. It's a fundamental problem that all solenoids have when pushed hard. I have a new handpiece that has a mounted fan which keeps the solenoid cool take a look here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Q9xFH1qhLhE.html

Having played around with those things myself, I'd say that using a Raspberry Pi for this is total overkill. If you must use a microcontroller (e.g. when you do not have access to an oscilloscope), I found that an ATmega168 does the trick perfectly well for both frequency, duty cycle and duty power control and could in theory asynchronously control up to 3 handpieces using non-blocking timers. The cheapest and most precise approach for a single-handpiece controller however, would be an all-electronic solution that works with two NE555 timer ICs (one for frequency and the other for duty cycle control). This would most probably require access to an oscilloscope though to set the correct timing on the duty cycle circuit.

I agree the raspberry pi is overkill I've used a Pico which is more like the Arduino and cheap under £5. it controls everything very well it just that I made an error 😮 and went on a journey 😉 and for most that have no understanding of electronics the 555 is out of the question.

Hi Jerry, it's possible that you have a duff speed controller or potentometer. You may be able to test with a 12v bulb completely separate from the engraving system. Other than that the most likely cause is that it's wired incorrectly but you haven't tracked it down yet. The wires from the speed controller feed the MOSFET the MOSFET then goes to the solenoid.

I followed your instructions but I used the solenoid that you mentioned Thin Tran uses.

@@jerrymanges2489 if you are putting 12v in to a pwm controller you will always get 12v out, it's the current that is limited by cycling the width of the pulses on and off very quickly. If you use a bulb or led as a test it's should dim or brighten when you turn the potentiometer. It should however switch off with the on/off button. The problem with pushing more power through the solenoid is that it will create more heat. It can be done programmatically by adjusting the delays. A longer delay after a write will allow the coil to be activated for longer. Different solenoid have different sweet spots so a bit of trial and error may be required for the solenoid you are using.

Thank you. The tool I use is the super easy graver to push up a stitch which the wire rests on when it's soldered. A stitch is a bit like the burrs that jewellery setters push up and then they round over the top to form a grain. The stitches are a bit larger. You don't need to use a powered tool you can use a spitstick (onglet) or a standard 90⁰ push engraving tool.
