Its a macro by Andrew Ellis to test a 3D printers motion systems capabilitys and its aim is purely to find out Speed and Acceleration Limits.

Thanks for the Offer but i am just starting off with my CNC journey and that seams like too big of a step right now. Maybe you could upload step files to JLCCNC or a similar service and have them maschine the parts for you.

As of Now for XY I am using LDO 2504s(LDO Speedy Power) 58V@2.5A with a Kraken Controllboard that has build in TMC2160s. I am also using andrewmcgr klipper_tmc_autotune plugin. Here is the klipper Config: [stepper_x] dir_pin: !KRAKEN:PC13 step_pin: KRAKEN:PC14 enable_pin: !KRAKEN:PE6 rotation_distance: 40 microsteps: 64 full_steps_per_rotation: 200 endstop_pin: KRAKEN:PC15 position_min: 0 position_endstop: 350 position_max: 350 homing_speed: 100 homing_retract_dist: 5 homing_positive_dir: true [tmc5160 stepper_x] cs_pin: KRAKEN:PD6 spi_software_sclk_pin: KRAKEN:PC6 spi_software_mosi_pin: KRAKEN:PC8 spi_software_miso_pin: KRAKEN:PC7 run_current: 2.5 sense_resistor: 0.022 stealthchop_threshold: 0 [autotune_tmc stepper_x] motor: ldo-42sth48-2504ah tuning_goal: performance voltage: 58 overvoltage_vth: 60 tbl: 1

@@VaporizationEnt Thank you so much! I hope you have a very good day ☺️☺️

On my MPCNC I am using 10mm Gt2 Belts with 4 E3D Superwhopper Motors.

Yes, Correct.

Thanks. I really like filming with a camcorder especially the optical Zoom.

Its called "Orbital Mantis" and is my own design based on "Mantis Dual 5015 Toolhead" by Long and StealthOrbiter by sneakytreesnake on Github. I am using the stock clicky probe from Longs repository. Currently it has no been published yet.

If you are still interested watch my latest Video, there is a Link in the discription to printables for the BETA release.

@@VaporizationEnt thank u sm man

That is a relic form a Time when I did not realise that yet. When I Got them the FEM simulations that thats decisions was based on were faulty.

@@VaporizationEnt Could you elaborate on the FEM simulations being wrong? Are there any articles or any other links to discussions about that? Also, what about the Y backers, are they still considered beneficial or just a gimmick?

@@MrGlibnes what i am refering to is a change in github.com/tanaes/whopping_Voron_mods/tree/main/extrusion_backers as far as I remember earlier simulation showed the backers to also work when on top of the gantry extrusion.That has changed since then. The Y Gantry Backers absolutly work well and as intended.

Yep, I am still struggling with that at very high speeds. The Outer wall flow and therefore pressure in the Nozzle is way lower than on the other features. I think it would be ideal to have a dynamic PA value that changes based on speed or always a constant flowrate that has little change and tune PA for that.

@@VaporizationEnt There is some talk about dynamic PA on the klipper discord, haven't look in it. I find that PA is tuned best by trial and error.

@@3DPI67 Very Interesting, Thanks for the Suggestion.

Its not very loud but also not quiet either, being in the same room while printing is fine but I would not want to sleep next to it. It would be way more quiet at lower Accels and Square corner Velocity.

@@VaporizationEnt Thanks!

Thanks. I am using a decent Quality PEI Springsteelplate from LDO with the Bed at 110C and a Nevermore for Circulation with Filtering and heating of the Chamber Air. I let the Bed and the Printer heatsoak until the Chamber is close to 60C.The ASA from 3Djake has a Low tendency to warp and in a Hot Chamber almost none even with alot of Airflow as long as it is Hot Air. For the First Layer I use .25LH and 120% Extruison like Andrew from ellis3dp.com recommends.

No but similar, like the Evantis its also based on the Mantis. My Design uses an Orbiter 2 instead of the sherpa mini on the Original Mantis thats why its called "Orbital Mantis"

Tmc drivers have stallguard which lets u home without endstops, high chance he uses that.

The E Stop switch is hooked up to an Endstop Pin on the Kraken. And this is the Macro I found online: [gcode_button ESTOP_BUTTON] pin: KRAKEN:PC0 press_gcode: {action_emergency_stop("Emergency STOP was pressed, Powering Down!")}

@@idranoutof1d On my Voron 0 I do use sensorless homing but the 2.4 has endstops.

@@VaporizationEnt Great, Thanks for the reply!

The TMC2160 Drivers and TMC autotune script are to thank for that!

@@lnfotron Its a Python Script by andrewmcgr on Github. Unlike real servo autotuning with a feedback loop, it only calculates values for most registers of TMC stepper motor drivers from a spreadsheet.

Yes, I agree. I am working on that. The End-Goal is to print really fast and still have structual integrety for egineering parts.

Its Mainly the LDO 2504s @2A RMS. Currently im still running 24V on an Octopus with TMC 2209s. Because the 2209s are operating at their absolute Limit I will be switching to a BTT Kraken soon.

As of right now: LDO 2504 XY Motors 24V @ 2A runcurrent, No AWD, Mantis Toolhead with Orbiter extruder, Ge5C bearings on the Gantry couplers, Light weight Alu X Beam and Ramalamas Idelers. There are more mods on the printer but they dont really effect printing performance as much.

Looks like a nice Setup! I have also started Development on a CrossGantry Printer focused on high printing Speed, stay tuned for Updates on that.

@@VaporizationEntamazing

Minor step losses might be occuring as I am scraping at the limit of this setup, but the printed model functions as intended.

@@VaporizationEnt nice,im also planing to mage the zerog upgrade to an ender 5plus,i was thinking to use those stepper motors that have rotation sensors on them. In any case nice setup 😁🤜🤛

@@62arts Cool, hopefully closed-loop 3D printing systems will become more common in the future, that would be great.

When it comes to speed yes, but I have jet to see an Ender 3 with a 350mm x 350mm x 300mm Heated 60+C chamber.

I have put some insulation on both sides, top and back. I am running a Nevermore under the Bed and put heatsinks and fans on the XY Motors. The Active Motor cooling using fans contributes a lot to the overall chamber Tmp.

Its mostly the very light "Mantis" Toolhead in combination with LDO Speedy Power Motors (LDO 42STH48-2504AH) running at 24V 2A for X and Y.

nice! i start skipping steps around 400 mm/s, but I haven’t tried upgrading the motors yet. Thanks!

Yes, watch my latest upload for proof

The Parts that I have printed this fast all work well. With the Stealthburner I have run into some part cooling limitations for smaller parts and I had to increase Hotend Tmp from 250C to 265C to achieve the nessesary flow rates.

​@VaporizationEnt have you considered the xol toolkit? It's supposed to have better cooling than the stealthburner.
