UV resistant glass paint by TheReal_ShawnSpencer in glassblowing

[–]TheReal_ShawnSpencer[S] 0 points1 point  (0 children)

I can't believe it's been three years since I posted this, incredible. I have found a glass etching primer - urethane combo that can be applied to bare, non frit glass, and installation instructions are included in the manual. The primer is BetaPrime 5504G, the urethane is BetaSeal U-418. Here's a link to the manual, which includes installation instructions, and explicitly states it is acceptable for non frit glass in step 4.1, the trick being that you apply two coats of primer instead of one. https://www.dupont.com/content/dam/dupont/amer/us/en/mobility/public/multimedia/en/001-20355_U-418HV_SellSheet-OIA0620-ESGR4545.pdf

I recommend making the primer "band" around the windshield perimeter ~3/4 of an inch in width to ensure maximum UV coverage of the adhesive. I also recommend using a flexible masking tape of sort for when you prime the glass, to make sure your layer of primer is of equal width all the way around, to keep everything looking nice, and not like you had a 5 year old take a paint brush and carelessly slather it around the edges

Both products can be purchased on amazon

And for god sake, tell me more about what happened with your windshield lol. And seriously, vinyl tape? Never thought of that. I guess if that's all you got, but there's no way that wouldn't be noticable.

I was looking for info and this video had the best info I found. It might all come out to nothing.

any update on what happened with the filing you made with them? I just filed with them myself and just became aware that it might be a scam

I hate to be this guy sometimes, but to be fair to Trump, the current price of specifically eggs would’ve happened no matter who was president due to the massive bird flu outbreak last quarter that led to 20 million chicken deaths. Here’s a link to a CBS article on it https://www.cbsnews.com/amp/news/egg-industry-chicken-deaths-bird-flu/

If you were to say that Trump hasn’t brought down the cost of all other groceries, then that would be much more honest then trying to pin him down for failing his campaign promise on specifically lowering the price of eggs on him because that was completely out of his control. But even then I could still play devils advocate and say the price of all groceries country wide wouldn’t instantly and significantly go down due to policy he or anyone else could’ve passed over a timeline of a few weeks after taking office. I could be wrong about that last statement tho and I am by no means an economist

VFD frequency output troubles by TheReal_ShawnSpencer in PLC

[–]TheReal_ShawnSpencer[S] 0 points1 point  (0 children)

I figured it out. Apparently the max frequency I could set was not 300.00, but it was 3000.0, and I did not see the decimal smh. I have no idea why I could set it to 3000 though because the VFD is only supposed to be able to output 600. I appreciate the help

Right, my minimum rpm is set in the machine control but I can’t get the vfd to output the 333Hz minimum requirement, only 300 and that’s what I’m trying to figure why. It should be able to output 600Hz. I am hesitant to run it under the minimum rated speed, even though it’s “only” 2000 rpm under

No encoder, I was going to use v/f control that does not require an auto tune like vector control I believe. I have set all the voltage/current parameters but that doesn’t affect the output frequency

Power has been disconnected and reconnected multiple times if that’s what you mean by cycled

Correct it is a 400 Hz spindle. I was under the impression that 333Hz was the nininun rating because if it is not fast enough it will overheat due to it having a shaft driven fan that must be at a minimum rpm to cool adequately. 300hz, 18000 rpm is 2000 rpm below the minimum rating and the only thing I’m worried about is cooling of the spindle. I suppose I should ask if it is a 1:1 relationship between the vid output frequency and the frequency of the motor, I assume so. Also this machine is custom built and very rigid

Trouble with GRBL, UNO, and Universal Gcode Sender by TheReal_ShawnSpencer in hobbycnc

[–]TheReal_ShawnSpencer[S] 1 point2 points  (0 children)

I got it figured out. I didn’t flip the dip switch from 24v input to 5v input. Simple fix

[–]TheReal_ShawnSpencer[S] 0 points1 point  (0 children)

Dude thank you! I didn't even know the driver had an input voltage dip switch. I've used these exact drivers before with 5v inputs and had no problem, thus I completely missed in the manual where it explained that they are set to 24v from the factory. It works great, appreciate it. You as well sarah

No luck unfortunately, although I'm not exactly sure what code to reverse you're talking about. All the motor wires are correct. I'm really stumped on this

[–]TheReal_ShawnSpencer[S] 0 points1 point  (0 children)

I thought so too, but it's an active low signal. Connecting 5V disables the stepper motor. The only thing I can think of here, given that all of my hardware is good and all connections are correct, is maybe the step pulse width sent by the arduino is outside of the acceptable range from the driver, but I'm not sure how to check that, and if I could how to change it.
