@AndrewBCN, Could you please describe the changes that are depicted in each of the pictures above? I find the pictures are not enough to adequately understand what is being done. Thank you!by NickE - RAMPS Electronics
Teacup now supports Delta Kinematics! Today, I was able to successfully do a test print using Teacup. It is only the lowly 15mm test cube done at 30mm/s, but it is the culmination of many hours of effort. I know, I know - without evidence, it didn't happen: YouTube Also see attached picture of the finished test cube. Rudimentary LCD support for the RepRapDiscount Smart Controller has also bby NickE - Firmware - experimental, borrowed, and future
@dc42 and @ambrop7, Thank you both! I am studying your code with your explanations. I hope to incorporate your approaches in my own work someday. NickEby NickE - Firmware - experimental, borrowed, and future
Either of the two below work for the Reprapdiscount Full Graphic Smart Controller on the RAMPS1.4/Mega SCK = 23, MOSI = 17, CS = 16 (corresponding to the Mega's Pins). Uncomment one the two lines from the sketch. //U8GLIB_ST7920_128X64_1X u8g(23, 17, 16); // SPI Com: SCK = en = 18, MOSI = rw = 16, CS = di = 17 //U8GLIB_ST7920_128X64_4X u8g(23, 17, 16); // SPI Com: SCK = en = 18, MOSI = rw = 1by NickE - RAMPS Electronics
@dc42 and @ambrop7, Looking at your firmwares, I am trying to get the flow of what is happening, but it looks like it will take hours of code analysis Can you please give me a simple flowchart or pseudocode of the steps being taken to calculate the step times? I would appreciate it very much!by NickE - Firmware - experimental, borrowed, and future

I have been using my Reprapdiscount Smart Controller since last May with no difficulties. During a print, the display changed (see attached image) to where the first two lines are fine, but the last two lines show blanks for the first 8 characters and white blocks for the last 12 characters. The menu still functions normally (except you have to know or guess what you cannot see). The SDCard paby NickE - Controllers

I bought some red and blue filament from this ebay supplier: . It was supposed to be 1.75mm ABS. The boxes the spools came in were marked as: ABS 1.75/BLUE/140115ABS002 and ABS 1.75/RED/130819ABS008 but the spools themselves were not. The spools were vacuum sealed. The filament, however, is not (as far as I can tell) ABS or PLA. It prints very well at ABS profile with extrusion at 230C and hby NickE - Plastic Extruder Working Group
