@_discord_139570952085176320:t2bot.ioSoftdrink#0282 maybe ABS would also work 07:59:12
@_discord_139570952085176320:t2bot.ioSoftdrink#0282 both of those materials make very very durable parts when properly printed, but they can be finicky to work with 07:59:46
@_discord_636793905077288970:t2bot.ioGolden finicky how? 08:02:39
@_discord_139570952085176320:t2bot.ioSoftdrink#0282 For this question though - are you talking about reducing the deadzone, or the throw?

At least in my mind these are two very different concepts - deadzone is the region in which you can move the lever before it starts to engage a signal (be it a switch or some kind of analog threshold), where throw is the total distance you can move the lever before it stops moving (EG: by hitting the gate)

@_discord_636793905077288970:t2bot.ioGolden oh, sorry, i should have been more clear 08:06:10
@_discord_636793905077288970:t2bot.ioGolden I'm talking about throw 08:06:21
@_discord_636793905077288970:t2bot.ioGolden since this Sanwa is analog i can make the actuation distance whatever i want 08:06:50
@_discord_636793905077288970:t2bot.ioGolden assuming i can properly program an arduino 08:08:11
@_discord_139570952085176320:t2bot.ioSoftdrink#0282 Hard to explain tbh, especially since I haven't done any printing with them myself. But from what I've heard:

- ABS needs constant high temperatures during the main print process, and needs to have slow changes in heating/cooling cycles. So usually a good ABS printer needs a full sealed enclosure and a good heated bed
- Nylon IIRC has issues with stringing and layer delamination, but I haven't used it myself so I don't know the details.

08:08:32
@_discord_636793905077288970:t2bot.ioGolden i managed to do it, but the code has one flaw 08:08:39
@_discord_636793905077288970:t2bot.ioGolden I see. how much would it cost for me to send a CAD file or similar to a printing company for something that small? 08:09:38
@_discord_139570952085176320:t2bot.ioSoftdrink#0282 Probably not very much, and many of them will give estimates for free if you upload a model 08:10:29
@_discord_139570952085176320:t2bot.ioSoftdrink#0282 But in your case I think you probably want to tweak the gate, not so much the actuator 08:10:46
@_discord_139570952085176320:t2bot.ioSoftdrink#0282 Although looking at the picture you posted it is hard to tell how the geometry works on the lever mechanism 08:11:38
@_discord_139570952085176320:t2bot.ioSoftdrink#0282 does it even have a 'gate'? 08:11:45
@_discord_636793905077288970:t2bot.ioGolden the square-ish plate with the circle is the "gate" 08:14:45
@_discord_636793905077288970:t2bot.ioGolden it has been detached from the lever 08:15:00
@_discord_636793905077288970:t2bot.ioGolden the hexagonal white piece is the actuator 08:15:29
@_discord_636793905077288970:t2bot.ioGolden this is someone else's being disassembled. it's really hard for me to take pictures of it myself without taking it apart 08:16:57
@_discord_139570952085176320:t2bot.ioSoftdrink#0282 mmmmm 08:26:59
@_discord_139570952085176320:t2bot.ioSoftdrink#0282 so to be clear then - the hexagonal piece rides against the circular cutout of that metal plate? 08:27:20

@_discord_139570952085176320:t2bot.ioSoftdrink#0282 The best way to reduce throw then would probably be to make a plate with a slightly smaller diameter hole 08:27:46
@_discord_139570952085176320:t2bot.ioSoftdrink#0282 I'd recommend prototyping with something easily obtainable and cuttable by hand, like plastic sheet from a hobby store 08:28:14
@_discord_139570952085176320:t2bot.ioSoftdrink#0282 and you could probably order a proper one from lasercut acrylic or even waterjet from thin sheet metal 08:28:41

@_discord_139570952085176320:t2bot.ioSoftdrink#0282 It depends on how thick that part needs to be 08:29:17
@_discord_636793905077288970:t2bot.ioGolden yes the hexagonal piece rides against the circular cutout of that metal plate 08:30:45
@_discord_636793905077288970:t2bot.ioGolden an expert on this (who almost begged me not to 3D print for levers) told me my best bet is to change the hex part, but that's if im not "jury rigging" like i am now. why is changing the plate better in this case? 08:35:11
