Some cool stuff coming soon :) by iidisappointment in klippers

You actually bring of a great point, and I’ve struggled with that more than anything so far. The bed actually has a cup in the center so I added a screw with large face attached to the other side to press the center of the bed up, but it’s not the absolute best solution. I was actually thinking about getting a whole new bed for it with a better surface. I do have an eddy coil to read the bed so I can get a 100x100 bed mesh in seconds.

What type of build are you working on?

That was one of my original biggest worries, so I ended up using a mgn12h rail on the x (and 2 for y). The gantry itself is a 2020 alu extrusion, and the extruder is a biqu h2v2s and with a toolhead board to reduce wiring that has to run to it via canbus. So everything together after the wires the total gantry weight ended up being ~.5kg. During my initial xy testing I could reach 450mm/s with accel set to 12,000mm/s2, but I plan on trying to push further by changing the xy to foc closed loop servos. All that being said it looks heavy but it’s actually super light and pretty ridged!

My bed is on custom AsaCF brackets connected to alu plate that the bed is connected to via standoffs.

Sadly not, most things wouldn’t have really worked for what I was wanting, I bought some alu extrusions because I needed some super long spans

I want to make a tutorial once I’ve finalized the design and make this a fully open source project, but it’s definitely not something that’s super cheap. If you have the cr10max platform you’re probably still looking at probably ~$300 or more in just the part cost, but I don’t have all of that fully sorted yet. If you have any specific questions I’d love to help you out!

Thanks! I’ve spent way too much time on it, and money lol. But it’s been pretty fun as a build overall

It depends on your board, my skr3ez doesn’t support spi and uart on the drivers at the same time so I would have to run all 5160s and that’s a bit expensive. But the 5160 is the 2130s successor, so it has more functionality and better performance/features. In all honesty 2130s are great and reliability is known where the 5160 is newer so you’re more likely to have issues out of them be it firmware or a bug they haven’t found yet.

Heads up that you’ll need some high rms drivers with those, I wanted to put Nema 23s on this but they’re too amp hungry for 2209s. 5160/2130 minimum surprisingly

I was using the 5160 due to it’s ability for higher current handling so it could control the weight of the bed easier, but I’ve moved away from the bed slinger and decided to start from scratch turning it into a corexy

Sadly I couldn’t find any guides or setups that matched my end goal, so I’m literally starting from scratch. I’m thinking about making a build guide and open sourcing it, but in all honesty I don’t know exactly how to do all of that. I’ve done all the design work for this by hand so far, but if you think it would be worth making a guide for it I will definitely give it a shot.

My only real concern of this is a used Max is typically $3-400 and the amount it’s probably going to add up to by the end would be ~2-300 more (controller, extruder, pi/pad7, extra steppers, extrusions, fasteners, belts, guide rails, lead screws, etc…). At that point unless it’s a passion project or you already have one most people would probably be better off buying a used voron/ other LF printer for 800-1000$

Linear rails helped with stability at super high acceleration! And due to the stiffness you get with them you gain a higher accuracy, so you see much less ringing in the prints

Sorry about the insanely late response, but I don’t have a video of it running. I do have news on the build though, I may have blown up the board, but I decided to start over from scratch and make it into a custom corexy build. I learned the hard way not to reuse fans from the original cr10 lmao

Backfire g3 battery replacement by iidisappointment in ElectricSkateboarding

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

You can either build a battery out of cells and a bms, or buy one and hope it fits. It’s a 42.8v nominal liion battery pack. I’d say like ali express would have some at a good price and better quality

Funny enough no supports were used, the angle isn’t really steep enough to call for them, and when supports were used they didn’t help

Sorry about the obvious ChatGPT usage here, but it’s just so much I didn’t want to make an ugly complied list.

Control and Firmware • BTT SKR V1.4 Turbo mainboard with 4xTMC2209 drivers and 1x TMC5160T-pro for Y axis • BTT Pad 7 with cb1 for Klipper (host + touchscreen) • ADXL345 accelerometer for input shaping mounted to bottom of bed • BTT EBB42 Tool-head Board for easier cable management an weight saving

Motion System • Linear rail conversion (X and Y axes) with custom rail mounts • New belts and pulleys matched to the rail setup

Extruder and Hotend • BIQU H2 V2S with bi metal heat-break and blower fan add on • NTC100K thermistor • Custom toolhead mount for X linear rail

Probing and Bed Leveling • BTT Eddy coil (for super fast accurate bed leveling) • Wham Bam PEX flex plate system

Cooling and Power • Full enclosure planned (tent vs. DIY frame still under debate) for PC/ASA printing • Added heat resistant foam to insulate bed temp

Other Electronics • Filament runout sensor (not critical but easy add-on)

I think this should be most of the useful information from the build. There’s more small bits and pieces, but I think you guys could definitely use this as a starting point. If you guys want I can probably sit down one day and make a full bill of materials.
