No. But I'd adjust the latch to gain more bolt engagement.

@@RanBao There's no latch adjustment and it's already the tall latch.

Mine only feed in the range but not in the field. I ended up with getting the accuracy international at-x for the reliable feeding.

@@RanBao Can I suggest that add some notations to this video then or take it down? People (like me) find this video when researching parts, buy a given combo of parts based on someone claiming "look how great this feeds!" only to find out that it actually doesn't feed and the video is misleading.

Hello. The powder residue will eliminate any static charge after few cycles so you don't need to worry too much about that. Also feel free to join our discord if you need further help. discord.gg/ZhdThA2vrW

Yep. You can find them here github.com/eamars/OpenTrickler-RP2040-Controller

Yup you're right.

@@RanBaoAwesome, what a useful capability in a $1k chassis.

Yup

It is the automatic powder dispenser that I designed github.com/eamars/OpenTrickler

Yeah 5 round pmag works for me.

@@RanBao thank you sir!

Yes

This is in Ashburton.

Sorry I'm still waiting for my 6mm br barrel. Unfortuantely I don't have access to any 6br rifle at the moment.

I have a mass driver that I currently use on a Glock 23 build that I have converted to 9mm. Have had no issues at all with cycling or feeding. I will also occasionally use it with my Glock 23 oem 40 s&w barrel since they are similar rounds, and that functions well with no issues too. For the price you can’t beat the mass driver, strike industries really does make great products. My current go to comp is the radian afterburner and ramjet, which I use on my psa dagger build….if you have the money go for radian but you can’t go wrong with this. Strike industries also has replacement parts kits for the mass driver which is less than half the price of the whole mass driver kit….20 bucks for the guide rod and spring….a couple dollars for little washers that it uses

No feeding issue at all.

DOUBLE ALPHA PDR PRO-II G19x+mass driver has the identical length with the G34. If a holster can fit the G34 then it will fit this setup.

6mm br

Stock G19x barrel and Gen5 mass driver comp.

Is there a mass driver compensator made in particular for the 19x? Or did you use the option for the 19?

I don't maintain that design anymore. You could find more information here: github.com/eamars/OpenTrickler

The tolerance is set to 0.02gr. There is no way it will underthrow given how the controller is designed. Howver it would overthrow if a chunk of kernels are thrown at a time. I'm still tuning the PID controller between the speed & chance of overthown.

@@RanBao in my case I'm not that concerned about speed, slower and spot on is good. Some overthrows aren't an issue, like the commercial ones the average time for a batch isn't be even if you're getting 10% failure.

The current design is usable in terms of the powder trickling. Given the assembly manual is released I'm incline to make major changes to the open trickler body and the A&D FX12oi/300i shield. On the other hand the RP2040 controller board is closed to v1.0 release, no more hardware change is proposed at present stage. I will focus on the software design and system integration in next few weeks.

@@RanBao Thanks for the info, helpful.

The design is already made open source on my github: github.com/eamars/OpenTrickler The assembly instruction is also available: github.com/eamars/OpenTrickler/blob/main/Manual/assembly.md At present stage the user need to print and assemble everything including the PCB and printed parts.

@@RanBao nice, I wish I had the skills to do stuff like this. I don't work with Pi or 3D print.

那必须

Agree. Flow and heat dissipation is a big challenge for the Stealthburner. I was running Dragon volcano on this speed run but the extrusion speed can't really catch up.

@@RanBao I gotta get my hands on a voron to try to get it printing speedy to experiment with

It was the phaetus rapido

Yes I'm using a dedicated 55V PSU to power all motors. It is work upgrading for at least AB drives which will gives you crazy fast speed and acceleration.

@@RanBao i mean, is there a way to support 2 different stepper drivers in the same board if it’s setup correctly in klipper? i know klipper supports multiple boards with any assortment of drivers but i’m not sure i can use two different drivers in the same board. i’m running a btt manta m8p so i could leave the 4 z & extruder motors with 2209’s & the dual AB motors with 5160? it does make sense. thanks for the response btw! looking forward to having my 2.4 up & running ✌️

@@RPista If you're using board that allows variable external voltage source, like an Octopus Pro then you can run 2x 5160 for XY and the rest for Z and extruders with 2209. Klipper supports this mode without issue.

Here you are github.com/eamars/voron24_250_klipper_config/blob/main/printer.cfg

@@RanBao You are a rockstar. Thank You!

LDO 0.9 degree motor, driven by 5160pro at 55V@1A. The slicer is configured to print with 20k acceleration at 385mm/s speed.

@@RanBao That's good. Did not expect them to be 0.9s considering the sound. Thanks for sharing.

Hi The project is now having a face lift! github.com/eamars/OpenTrickler

How is it not good

Roughtly 2-300 bucks. Will trickle under 15s.
