@@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?

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

@@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.

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.

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
@selvalss

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?
@selvalss
5 ай бұрын
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?
@selvalss

@@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.
