Re: Hlidskjalf, Dual CoreXY - 7 years ago
Quotedc42 Could it be anything to do with the changes to the Pins-RADDS.h file to support the additional heaters? LOL, No disrespect intended dc42. Just there seems to be a disconnect between the Due and current RRF build. As you're a Duet guy, don't expect you to have any means of testing builds for RADDS/Due. Various builds of Bossac don't communicate well with the Due, just check the Arduinoby prot0typ1cal - CoreXY Machines

Re: Hlidskjalf, Dual CoreXY - 7 years ago
Not ruling anything out ATM. Gonna roll back and try as a base build, just as a CoreXY. Maybe even give Repetier a go, as it supports the PanelDue with json, though would need to add CoreXYU.by prot0typ1cal - CoreXY Machines
Re: Hlidskjalf, Dual CoreXY - 7 years ago
Well, the new Due arrived along with yet another microUSB cable (now have 5). At least it's new, nothing else was. Same "Device not found" and "SAM-BA operation failed" So tried different flavors of Bossac, seems the Due likes the version dated 11/3/2015 (from Arduino IDE 1.6.1). No problems connecting to the 'bossac programming port' and writing the bin to flash. Doesn't care which USB cable eiby prot0typ1cal - CoreXY Machines

Recommend Slick 50 One Lube, a short shot on each under-side on the bearings. Move while still wet to circulate balls. Not only is One Lube a rust preventative, it also deposits a micro layer of PTFE. You can also spray some on a cotton rag and wipe the rails down to clean them.by prot0typ1cal - Mechanics
Re: Hlidskjalf, Dual CoreXY - 7 years ago
Ordered a new Arduino Due R3, should have it in a few days. Tried everything with the old board: Bossa, bossac command lines from Arduino IDE hardware tools and Bossa, both native and programming ports, resistor dump from RX) to GND, etc... Runs sketches from Arduino IDE fine (blink), just won't boot bin files from flash, even when 100% verified ,no response in serial monitor. And yes, tried 4by prot0typ1cal - CoreXY Machines
Re: Hlidskjalf, Dual CoreXY - 7 years ago
Thanks o_lampe Still having issues flashing the bin. The comment in the inf file says "pre 1.18" for the driver you posted. Trying to flash RRF 1.19beta8. Odd thing is that if I use Arduino IDE can upload the blink sketch, over the programming due port, and it runs fine. Cannot get Bossa or command line bossac to upload with the programming port, get either SAM-BA failed or no device on com. Upby prot0typ1cal - CoreXY Machines
Re: Infills with a bigger second nozzle, how? - 7 years ago
You may not have to switch nozzles. It's possible to print 0.1 and 0.3 layer heights with a 0.4 nozzle. Unfortunately I've only seen this option for supports via the Makerbot slicer. Model as 0.1 and supports as 0.3 Be cool if you can do this for perimeters and infill, with or without nozzle (print head) swaps. doh, nm. Didn't read the op clearly. Just add a few more perimeters, the small gapsby prot0typ1cal - General

Plugged in a 4x20LCD/SD for RADDS, blank screen. Obviously something is wrong, gotta narrow it down before ordering replacements. Bummer is the controls were the first thing I purchased for this build, almost a year ago.by prot0typ1cal - CoreXY Machines

Re: Hlidskjalf, Dual CoreXY - 7 years ago
I'm concerned either the due or RADDS is bad, most likely the Due. Flashed it more times than I can count using both Bossa and command line bossac, each time the verify said all's good, yet no response sending commands over the USB. COM port won't stay connected. Seriously don't need these problems. Have a few more things to try before taking a hammer to it.by prot0typ1cal - CoreXY Machines
Re: Hlidskjalf, Dual CoreXY - 7 years ago
@dc42 Posted the "fix" on the duet3d forums. Though don't exactly know the why. Used Bossa to write my due, plugged Due into RADDS, put all the SD files in sys/ folder and inserted micro SD card into the RADDS, connected up the PanelDue, powered up... Panel Due says "connecting" only never does. from the config.g M575 P1 B57600 S1 ; Comms parameters for PanelDue PanelDue is also set at 57600by prot0typ1cal - CoreXY Machines
Re: Hlidskjalf, Dual CoreXY - 7 years ago
Downloaded beta8 bin and wrote and verified it to the Arduino Due. Powered up and now the PanelDue is stuck "connecting". Traced all the leads, all contacts are solid on the 4 pin outs Tx to Din and Rx to Dout, obviously V+ and gnd are correct otherwise there'd be no display at all. config.g and PanelDue both set at 57600 baud.

Re: My CoreXYU Printer project - 7 years ago
Cable management usually last on the check list. Waiting for my printer to work so I can print a control case. 3D printed parts can be as strong as aluminum, just need to be bigger and add more fasteners. Your printer looks pretty sturdy, with a massive build volume. Well done. Glad I could be of inspiration. Only wish I could have finished mine 1st, LOLby prot0typ1cal - CoreXY Machines
Re: Building a LARGE corexy printer, and need advice. - 7 years ago
I'd use rails for the Y and Z, and anodized aluminum tubes for the X rods. Larger the diameter the better for the span. Drop the hot end between the X rods, and calculate the center of gravity for the carriage to be on plane with the center of the X rods for least deflection (moment of inertia). Stay away from Titanium, unless you can get it hard anodized (type III). You can buy hard anodized aby prot0typ1cal - General
