Dunno if you're still around, but i've been using your github link; i really appreciate the info you put in and the work! I'm feeling pretty close to getting it, just not having a lot of luck getting a nice even imapct. I have a few solenoids coming in the mail, and am probably going to try to make one, but either way, thanks! Also.. oh, i found a company selling a solenoid graver now, and it's 100% for sure 3d printed, and it looks damn close to your model; the modes they describe look the same too, and they used the exact same pedal as the ez graver and yours; i think they're trying to patent it too... something like $2400 USD for the machine. ouch.
@@jasoncastle1741 I was mostly thinking about the part where the solenoid is attached to the 3d printed part or the part where I put the collet, since i'm eyeballing it it is not perfect, I tried to do it with steel but it is impossible with my tools. Are you interested in the circuit board?
@@selvalss Good afternoon. I am from Germany. Can I somehow purchase a kit? even in unfinished condition. I'm happy with this look, I just want to do my hobby without a pneumatic graver where are you from?
Thank you Matt. The files can be found at the OnShape page, it is called "Handpiece for solenoid 1642", from there you just have to select the pieces, on the left panel called "Parts", then "Export" and select the desired format as STL. If you click on the link you can see the other files from the same user and they will be there. Please let me know if anything is not working correctly.
Thank you for sharing your project and findings! I study jewelry making and I'm planning to build one to get into graver settings! Are you using 12V version of "perfect solenoid" and powering it with 12V?
Sorry, I was not that clear on the answer. I am using a 6V rated power 1335 solenoid withe the handpiece from the OnShape site. The model is ITS-LZ-1335-D-6VDC. I am powering it with a 11V power supply.
@@selvalss Thanks so much for your clarification and all the experimentation on the solenoids! I found the handpiece on OnShape without problems. Looking forward to make one.
How much stroke/travel is needed for the solenoid to engrave well? I I would be curious to experiment with something else different than solenoids. Not sure if if it would work tho
It depends on the weight of the plunger and speed. So for an 6.4g plunger with a 12w power 6mm is enough for lots of materials. Right now the 1642 solenoid with 6 mm travel at 9w is an all round handpiece
Sir, how do you control solend energy? Just simple voltage control or maybe pulse by pulse current control? Do you have adjustable pulse frequency? What frequency range your are using?
Hi, I control it by the process of "bit banging" in a determinate frequency, its like I create the pulses with software that is installed in the board (or arduino if you prefer) and the pulses control the solenoid. The power is determined by the PSU (Power supply unit) I am using, it is determined by testing and trial and error, the idea is to have a solenoid that, given its characteristics, will give about 25W of power. The build can be checked on the github page in the description. It's possible to go from 0 to 40 hz for a bulky solenoid or from 0 to 80 hz for a small solenoid.
@@selvalss Thanks for your answer. Not sure about meaning of "bit banging" really :D Maybe you are saying that you are controlling pulse length while pulse frequency does have fixed value?
@@htchtc203 bit banging means turning on and off in defined intervals, theres no special curve being made. Right now the modes are: variable frequency with fixed power, fixed frequency and fixed power and fixed pulses in intervals. I am implementing in the future another mode that set a fixed frequency on a variable power.
@@selvalss Yeah, I just dont have the time. I also tried that Chinese one but didnt like it compared to the pulse graver which I tried earlier this year

@@briandanay2487 hi, if you need any help contact me on reddit. Why are you having issues gettting an even impact? What is happening.
Glad to see you are still at it I'd still like to help with machined parts
Hi, Jason. How about an exchage of help? Do you need something that I can also provide? Where are you from? Im in EU.
@@selvalss I'm in the US. But shipping isn't that expensive. What machined parts would help you perfect the system

This is an excellent video - do you have the stl files for the handpiece for the 1642 solenoid?

@@ericying hi, I am using now the 6v version and powering it with 11v. The rating voltage for the solenoid is when it is powered 100% of the time.

@@selvalss Any chance you know how many watts max it draws or the resistance of the coil?
@@ericying The resistance of the coil is 9 Ohms
What type of solenoid...?
Do you have a model number or link to purchase...?
@@אילןמאור-ה3נ hi, the solenoid models are pn the github page. Its a 1330 or 1335, 6v solenoid powered at 11-12v.

How much for that set? Can you build me one, similar to pulse graverr.
Check the construction instructions on the link in the description, there you can find how to make it yourself.
Still interested in buying one of these from you.....You sure you dont want to sell me one?
Hi, Ian. Check😁 your reddit inbox.
@@selvalss Yeah, I just dont have the time. I also tried that Chinese one but didnt like it compared to the pulse graver which I tried earlier this year
@@ians9390 which chinese one? The one from aliexpress?
@@selvalss correct. the kataway or whatever it's called. R-01
