My bad... I missed the tower angle parameter. Can you please detail what is the reference (zero angle) and how adjustments could be made on those parameters (clockwise or counter-clockwise)? I'll take a look at the code and compare it with code of firmwares that take the diagonal rod corrections per tower. Nonetheless I think you "virtual tower" method is very different from what is done is otheby micheleamerica - Firmware - experimental, borrowed, and future
I think I got it for the Z height and it should not be too tough to "migrate" my configuration to Klipper. The position and radius corrections are determined by the auto calibration procedure and serve to counter any printer mechanical issue (bad build to make it short), such as the angles between towers not being exactly 120°, or the length of the diagonal rods not being all exactly the same.by micheleamerica - Firmware - experimental, borrowed, and future
Thank you for the information. I've given a look at the example config file but failed to see entries corresponding to z-height, or the tower position and radius corrections. Is there a way to convert my current configuration to the klipper printer.cfg file? How did you implement your calibration values? And would you share your printer.cfg file with me? Thanksby micheleamerica - Firmware - experimental, borrowed, and future
Hi all I'm trying to see if this new firmware is an interesting addition to my home made delta printer. I have my printer pretty well dialed-in using the marlinkimbra MK4duo firmware running on a Due. Before committing to trying out klipper I'd like to know if it is possible to migrate the existing delta settings (which are the result of a G33 delta auto calibration) to the klipper firmware. As Iby micheleamerica - Firmware - experimental, borrowed, and future

Ciao Grazie. I thought the Menu folder structure was read during SD card insert and that a new dynamic menu structure would appear on the LCD screen. Regards Micheleby micheleamerica - GCODE, Software e Firmware
Ciao a tutti I'm running MK4duo 4.3.2 with my homemade Kossel XL Delta printer and everything is working perfectly except for one thing. I copied the Menu folder structure and all files within onto the SD card but I see no new menus on the LCD. Is there some special configuration (during compilation) required for this to work? Does the SD card require any particular format? Grazie Micheleby micheleamerica - GCODE, Software e Firmware
Well, I finally managed to find the issue. The configuration file that comes with the DUE version of Repetier has FEATURE_JSON as the define for the ESP8266 Duet web interface. I added the JSON_OUTPUT and now the firmware is accepting the M408 gcode and spitting out a properly formated JSON string. Now I only need to wire the NodeMCU to my RADDS board and see if things are working. In any caseby micheleamerica - Developers
I do not use the configurator, instead I manually update the Configuration.h file, and I do have the JSON_OUTPUT defined. Looking at the code it does seem that toxuins code was merged in the 1.0.0 branch but the thing is that I keep getting "invalid gcode" if I send M408 to the printer. Is there anything else besides the configuration flag that may influence this gcode acceptance by the firmwareby micheleamerica - Developers
Are there detailed step-by-step instructions on how to install the required firmware and Web code on the ESP8266 to have this working? The step-by-step instalation instructions in this thread have allowed me to install the Duet web interface in a spare ESP8266 and it seems to be running OK albeit without being connected to my printer. Is there any chance that the required M408 code will be implby micheleamerica - Developers
Thanks for all the pertinent answers. I think I'll ponder on this Kossel XL build some more time before committing to it. In particular the issues related to the reuse of the steppers and the controller. On the other hand I may start to procure the basic frame elements like the extrusions, fasteners, and the remaining vitamins... and even start printing the plastic parts. Again thank you all.by micheleamerica - Delta Machines
Thanks for your clear and informative answer. I fully understand the interest in having an existing and operational printer while in the process of building the Delta. I started my path into 3d printing by building a repstrap with everything I had available (wood, drawer slides...) and that allowed me to fabricate the pieces for the first iteration of my i2. I've got both a graphics and a textby micheleamerica - Delta Machines
Thanks dc42. I'll take a good look at the links you sent. My first idea was to go for the regular Kossel XL but moving from 1515 to 2020 extrusions to increase the rigidity of the frame and reusing as much elements as possible from my i2 (motors, electronics, endstops...).by micheleamerica - Delta Machines
Hi all forum members, I'm a proud owner of a Prusa Mendel i2 that over the past 3 years has suffered quite a few modifications (Z lead-screws, quick-fit carriage with dual J-Head hot-ends, and auto bed leveling, for the most relevant changes). Right now I'm envisaging the build of a Kossel XL using V-Slot 2020 extrusions but I'm unable to find a full and comprehensive BOM and build instructionsby micheleamerica - Delta Machines
I don't have bed autoleveling on my printer but I do know a bit of C. The # before the define means it is a preprocessor directive. It belongs there otherwise your code will not compile. In C comments start by a // or are between /* */ when they must span multiple lines. So in this case a line with //#define Z_RAISE_BEFORE_HOMING would be commented out. Put the #define Z_RAISE_BEFORE_HOMING lineby micheleamerica - General Mendel Topics
First of all thanks for the advice and suggestions. I'll try to do some trial prints to determine how best to do this. In the meantime I continued to google for more information and came over a study made by Joshua Pearce, an associate professor of Material Science and Engineering, regarding the quality of 3d printed parts and how certain fabrication settings influence that quality. He used (almby micheleamerica - Printing
Hi all, I need to print a few upgraded pieces for my Prusa i2 and would like to have some advice regarding the best settings for those prints. I'll be using PLA in 3mm, can chose between a 0.35 and 0.5mm MK5B J-Head and print on a heated bed smeared with stick glue (no issues at all with 1st layer adhesion). The slicer will probably be the Cura engine that comes with the 14.07 version but I alsby micheleamerica - Printing
Thanks for answering. Indeed I had not thought about that possibility but it does seem interesting. Do you happen to know about any x-carriage design suporting a direct extruder plus a bowden ? I have a Gregs Hinged Extruder mounted on a standard (original) x-carriage. And do you know if there are any extruder attachements to the two upper threaded rods that do not require the printer to be diby micheleamerica - General Mendel Topics
Hi all I'm thinking about upgrading my Prusa i2 to dual extruders but would like to keep a direct driven setup. Are there any such solutions ? X-carriage plus dual extruder setup to fit a Prusa i2 or should I go to a bowden setup ? Thanks in advanceby micheleamerica - General Mendel Topics
That is good news. And thanks for answering my question. Regardsby micheleamerica - Repetier
Hi all I'm in the process of moving from a GEN7 1.5 AVR (thank you Traumflug for this superb controller board) running Repetier 0.92 to a RAMPS 1.4 (that will have the same FW) in order to add an additional extruder to my Prusa i2. The GEN7 only supports 3 endstops (min) while the RAMPS supports both min and max endstops for each axis. I'm using 3 mechanical endstops with the GEN7 for the min oby micheleamerica - Repetier
I was having a similar problem that I solved simply by replacing the USB cable. The old cable was of bad quality in terms of insulation (very thin). The new one, besides being much better insulated comes with ferrite chokes on both ends. It was a life changer.by micheleamerica - Printing
