QuotePippy I wonder which firmware you're using for it ? It is regular Marlin. I used 2.0 but some may use 1.1.9by piper3d - CoreXY Machines
So Piper Infinity is a coreXY 3d printer with infinite Z or Y (depends on point of view). I was working on it during the last month and in the process of preparing a release. It will be available on Thingiverse and at https://piper3dprinters.com but here are few pictures of it and links to youtube videos. For early release files join FB group at https://www.facebook.com.

QuoteShank man I'm still able to get some good prints. I printed this largish print over the weekend. The printer was able to pick up the details. Wow looks great.by piper3d - General New Machines Topics
There were few changes in resent time. New Z roller with 2 additional holes to tighten bearings around the pipe in version 2, and optional version 3 update came out with updates replacing Z roller with Z PTFE sliders and 8 and 12mm linear rods conversion on XY.by piper3d - General New Machines Topics
Based on this picture tension of the belt, belt length and geometry of the gantry changes as Y carriage approaches idlers side. The belt should go free without "corners" from the motor to idlers. It may not be parallel to Y-axis but free from bending at Y carriage.by piper3d - CoreXY Machines
Congradulations with your build! It looks great! QuoteShank man After battling extrusion issues I was able to get this first print. Of the 4 RepRap printers I have made this is by far the best 1st print I've gotten. I still have some fine tuning to do, but I'm confident that I'll get some fairly good quality prints from It. Thank you! Check Piper 2 version 2 as well.by piper3d - General New Machines Topics
I can see how larger diameter idler pulleys may help. On smaller printers (with 6mm belt) I do not see artifacts caused by belt's/pulley's teeth, I did see it with a wider belt. I have designed my printer to fit 20 teeth pulley diameters so it was easier for me to twist the belt instead of redesign and use large pulleys.by piper3d - CoreXY Machines
Quotethe_digital_dentist The biggest problem I found was that it sucks moisture out of the air. You may want to look at "FilaDry" device. It promises to dry filament as it moves it from the spool to the extruder. It was shown at MRRF and it was feeding the filament from the spool drawn in the aquarium tank full of water to the extruder.by piper3d - CNC Routers, Mills, and Hybrid RepRapping
I know this is an old idea, but in order to use all toothless idlers, I have twisted belt between the motor and the first outer idler. I did this on the large printer (600x450) which uses 10mm belts. It did improve print quality by getting rid of repeating artifacts on the surface. At the same time twist in the belt have increased the elasticity of the belt and added to ringing/ghosting especby piper3d - CoreXY Machines
QuoteRoberts_Clif I have decided to build the V1 Engineering Piper. First C-Foot 3D Print in ABS looks promising, with ABS shrinkage the ID for the Feet is 23.37 the conduit measurement is 23.5. This means that very little finish work will need to be done in order to assemble the Piper 3D Printer. Robert, You have mixed up a little with names . Ryan's MPCNC is at www.v1engineering.com.

QuoteEzyMan 1- Is there any problem to change the hotbed to 400x400? 2- Is there any changes i have to do? in marlin? 3- Is there any risk regarding the power supply? 4- If i didnt change the hotbed and i put an aluminum plate above the current hotbed and i increase the heating temp. like from 60 to 90 degree as a special setting? is the printing will be ok? 1. Your bed will weigh more about 1.2by piper3d - General
QuotePippy We're not using 16 microstepping. Plus we're using 2:1 belt reduction - reduces the load on the motor and the belt. So you have effective microstepping of 1/8th. Aside from increased belt length, it is a nice idea. I may go for a similar belt schematics in the next generation of my printer. It opens a new way to tension the belt on Y carriage. Thank you for sharing.by piper3d - CoreXY Machines

Looks like your X belts are not parallel to X rail.by piper3d - CoreXY Machines
Quotethe_digital_dentist If motor B was moved up and segments A and J were longer, it would not affect operation of the mechanism. As long as segments A-H are parallel to the guide rails, and the belts have tension set to keep the X axis square with the Y axis, the mechanism will work fine. ... Equal belt length is completely unnecessary. I was referring to the symmetric system If your gantry isby piper3d - CoreXY Machines
Quote3DMind I even check the tension of the belt using the precise weight and pressing it to a specific point. It's pretty the same. The tension of belts will be the same as they are connected through X carriage, but if one belt is longer than other you will get a skewed structure.

Nice idea to shorten belts. Also, you may place motors on Y carriages instead of X. It may save X from weight load of motors and complexity of design but will keep weight on Y. I was too fast to jump to conclusions. It won't work on Yby piper3d - General New Machines Topics

I know it is off the topic but would like to hear an opinion. Quotethe_digital_dentist If you want to try to recover from a power failure or to shut down a print at night then restart it the next day, when the bed heats up... I do believe that restart is useful only for printing with cold - not heated bed. If the bed cools down the printing part will get off the bed.

QuoteTheHandsomeDog I’m having a hard time justifying the price of duet and panel without adding the expansion board into the mix. (Although it is a pretty cool solution) You may want to look into klipper, which my slash price more than in half by using Raspberry pi and 2 boards to expand the number of available stepper drivers for 3 or 4 independent Z motors.by piper3d - CoreXY Machines

Last time (today) I checked Lulzbot printers at microcenter they have been equipped with Wade's extruders. I heard Lulzbot have been moving to bondtech, but most likely because it is too expensive to make Wades extruders considering the cost of the local workforce.by piper3d - General
