Thought I might revive this post, I stopped posting on this printer as I ended up going to CoreXY, but the reason for reviving this post, is I am now going back to Dual Wire Gantry. But to build my printer as an IDEX. And Judging from the pictures I posted back 2018 my printer has changed so much since I last posted these pics. My printer is now a 2040/2060 extrusion frame, the aluminium tubiby Celcius1 - CoreXY Machines
Quotedustinoff Geometrically, 3 points define a plane, not 4. There is a basic physical problem with 4 point (4 dimension) leveling on a 3 dimension build plate. Picture this: (Using compass points for placement) points 1(N) is your ref point. Points 2(E), 3(W), and 4(S) are high. To adjust this you must simultaneously lower 2, 3, and 4, OR simultaneously raise 1 and lower 4. If you do not do itby Celcius1 - CoreXY Machines
If your looking for high accuracy Z drive, as has been used for the last 40+ years in CNC machines, are ball screws, if you spend the money, you can ones with an accuracy of 1um, and a closed loop stepper motor. you can go either expensive proprietary or cheap open source like a mechaduinoby Celcius1 - CoreXY Machines
Just to prove it can be done, my Printer uses 4 Z axis motors, and the experimental 4 point levelling system, Waiting on InsanityAutomation on the marlin git hub to fixes the issues I Identified, but I have it working on my printer. Please see picture attachedby Celcius1 - CoreXY Machines
I'm looking to go IDEX as well with my CoreXY but use the belt routing from a Dual Wire Gantry to control the second X Axis, which can move independent of the coreXY gantry due to the belt routing pattern, I have experience with dual wire gantry as my printer started out as a dual wire gantry and eventually went to CoreXY, but in saying this, with the second X gantry running independent of the coby Celcius1 - CoreXY Machines
Quoteblt3dp Drew it up like this. I'd put extra motor on whatever side is designated the X motor. Imagine the motor, green belt, and pulleys are on a different plane. Now I have to build it. Actually its simpler than you think if you use the Dual Wire Gantry method of driving, its on own belt and will only move when commanded )by Celcius1 - CoreXY Machines
Quotedc42 I revamped the support for CoreXY and related architectures in RepRapFirmware at the end of last year. The standard firmware binary now supports any architecture with up to 9 axes for which the movement of each axis is a linear combination of movements of the stepper motors. So if you come up with a new Core-based architecture with up to 7 independent print heads, RepRapFirmware will beby Celcius1 - CoreXY Machines
I have an offset bed probe, on my printer an IR one. But my one problem with the G33 routine, is that it does not take into account the offset of the probe, and I assume there is a reason for this, if that is the case. I’m looking to fit 3 offset probes to the effector and probe the XYZ offsets for each tower . How hard would it be to implement this, and then overlay the 3 probe tables to prodby Celcius1 - Firmware - Marlin
Nope the UART support is on 90% of reprap boards, and the RPi has the UART on the GPIO Anything that uses a Mega 2560 has an accessible Secondary Serial port that can run much faster than the USB, Just if you need to upload firmware changes, this is still done thru the USB whereas the communication with the printer is done thru the faster UART connection.

I recently did an upgrade to my printer, I have my raspberry pi powered by a buck converter off the 12V header on my Rumba board, and i've replaced the USB link with a direct UART connection running at 1 Mega Baud. And yes i'm using octopi. I'm doing this shortly with my new control board for my delta printer, I was wondering would people like me to put together a how to, on how to do this, youby Celcius1 - General
Hey Guys, Sorry I have not posted in a while real life unfortunately took over, but I have been working on my DW-G printer and have to say I'm going to CoreXY as the DW-G suffers from a similar racking issue as H-bot but it skews the axis (issue is with the Y-Axis) meaning calculation of the head skew is required no matter how stiff the frame, and this is as a result of the line coming in to tenby Celcius1 - CoreXY Machines

Hey Guys, Here are some pics of my printer I am building (excuse the mess). It has a build area of 350mm x 350mm x 410mm (Just measured the height of the print area), I use a Dual wire gantry for the X and Y movement, and its nice and sweet. and yes those are NEMA 23's yes I know its overkill but its what i had spare on the shelf! I dont know the full height of the Z axis as I have yet to implby Celcius1 - CoreXY Machines
I am also building a printer with 4 steppers in the Z-axis for the bed, but I have designed a daughter board, that takes the Z-axis commands and feeds it to all 4 motors but the board has one additional feature, I have a control circuit which tells which motor sees the step and dir signals, I’ve designed it to use one of the servo headers connection to send the “listen” command on telling the boaby Celcius1 - RAMPS Electronics

Hi Guys, I'm building a CoreXY printer, and using a Dual Wire Gantry drive system. ) But for the bed movement I'm going to go with the wire system as well for its drive, but cant decided whether to have a moving gantry or a moving bed in the Z axis. I'm leaning towards moving the Bed in the Z, but was curious, would it be better to move the gantry instead. Celcius1by Celcius1 - CoreXY Machines
Sorry I was typing my last message whilst driving, the ultrasonic detector I am designing is more a readily available distance mesausre than an endstop and the accuracy is actually 0.15mm to 0.1mm. The idea is, the arduino can get an accurate reading of the absolute position of the axis, so I can write a calibration routine into the firmware that using the ultrasonic sensors for the distance feeby Celcius1 - CoreXY Machines
Well to add I am working on an ultrasonic endstop using a 1.7mhz transducer to measure down to approx 10 to 5 um. I'll use this to get the absolute position at all times, and for self calibration. and see if it works for bed levelling too. But at this stage it's at design stage.by Celcius1 - CoreXY Machines
Hi Guys, I'm currently building my own CoreXY printer, as my Geeetech clone is on its way out so using one last time to build my next printer. Now I want to see if i can get rid of using end stops and replace them with rotary encoders to accurately track the axis position (alleviating the need for regular re-calibration), looking to use these optical encoders My Question is, what input do I uby Celcius1 - CoreXY Machines
QuoteDust look though the forums, every 3rd person asks how to build a over sized printer.. and we point out the obvious flaws in this idea. Cost: grows exponentially with size. Print time: grows exponentially with size. (Think months per print) Warping: grows exponentially with size.

Well I'm still going to see if I can build the printer that big, but I want to see how much I can push it, and to try and get the print speed as fast as possible. I want to see when I go up in size if the limitations on speed are reduced accordingly. Cause when the printer gets larger your print speed in reality needs to go up accordingly. So that’s why I mainly asked for help with the electroby Celcius1 - Prusa i3 and variants

Hi Guys, I was on a road trip with a couple of friends, and my best mate and I do work in graphic design and electronics, and was discussing a possible new way of using the resin from SLA printing in a different manner.
