Quotespota 4) Recipes Here I will list a number of possible recipes for UV-curable resins. The list below is just a start and I'm sure a wild variety of different ones will emerge and evolve in time. I have created a small spreadsheet to calculate the prices of these mixes. I will show the price as well. Pot-life of all these resins can greatly be improved if they are kept away in dark places anby yogesh.dp - Plastic Extruder Working Group
hello people, i want to try different photo initiators for fun to do resins (http://makemendel.com/catalog/category/view/s/uv-resin/id/152/) & makerjuice G+ (http://www.makerjuice.com/shop/gplus/). if anyone know what are the different photo initiators or compounds that are compatible with above two resins please let me know. i want to add those compounds or photo initiators to both of the rby yogesh.dp - Plastic Extruder Working Group
@Dust thanks for sharing this information. I really appreciate it !! as i'm new to this area, i don't know how to make these jumpers ON (high). If you have any information, any video link please share it thanksby yogesh.dp - Stepper Motors, Servo Motors, DC Motors
QuoteDr. Bogger They are set to 1/16 Micro Stepping Mode, however, I get the same issue in 1/4 and 1/8 mode. how to set 1/16 micro stepping mode ? please help !!by yogesh.dp - Stepper Motors, Servo Motors, DC Motors
@didzix how did you set 1/16 micro stepping on ramps ? will you please explain ? and does microstepping decreases layer height ? any help appreciated !! thanksby yogesh.dp - Stepper Motors, Servo Motors, DC Motors
how did you get the 1/16 micro stepping mode ? will you please explain ? I want to do microstepping for my nema 17 motor any help, much appreciated !!by yogesh.dp - Stepper Motors, Servo Motors, DC Motors
@karagad what actually "command 0.1" means ? where this value is in the marlin ? please help !!by yogesh.dp - Stepper Motors, Servo Motors, DC Motors
@mikadoh what jumper actually means ? how they are required for microstepping ? how to do microstepping .. any help much appreciated !!by yogesh.dp - Stepper Motors, Servo Motors, DC Motors
It turn when I command 0.1, but in bigger value, like 10, only noise. 0.1 what is this ? where it is in marlin ?by yogesh.dp - Stepper Motors, Servo Motors, DC Motors
Quotebonze77 Solved It was a firmware problem -_- // For Inverting Stepper Enable Pins (Active Low) use 0, Non Inverting (Active High) use 1 #define X_ENABLE_ON 0 #define Y_ENABLE_ON 0 #define Z_ENABLE_ON 0 #define E_ENABLE_ON 0 // For all extruders hey, are you sure about this ? because, my marlin have same code which you written here, but still motor doesn't move !! helpby yogesh.dp - Stepper Motors, Servo Motors, DC Motors
does anybody know how to do microstepping? I'm currently using nema 17 on full step & having the same problem. at some point motor rotates while sometimes it completely stops, making noise with vibration every time. Wiring is correct as far as i know because motor starts rotating as soon as i upload the test firmware. So, if anyone have solution please help !!by yogesh.dp - Stepper Motors, Servo Motors, DC Motors
Quotemisan Arduino IDE stepper motor library and examples have nothing to do with RAMPS and they are not expected to work with it. thanks but I've seen so many videos & posts that uses ramps 1.4 with arduino mega 2560 & a4988 motor driver module. i want this combination to be used in my dlp printer for z axis movement only. I tried with test firmware set up worked for first but now its sby yogesh.dp - RAMPS Electronics
@kabory thanks for the information about test firmaware & I have tried it with SMPS of AcBel PC8061 + Ramps 1.4 + arduino mega 2560 + nema 17 stepper motor + a4988 stepper motor driver module. thank god it worked. stepper motor started running when i uploaded test firmware but unfortunately motor isn't running when i upload the stepper motor examples from arduino IE. if anybody have solutionby yogesh.dp - RAMPS Electronics
So, does your motors moving now regardless of endstops ? if yes, then how u did that ? which test program you have tried ? I'm facing same issue with my z axis motor please helpby yogesh.dp - RAMPS Electronics
Even I am facing same issue. Currently, I am using Arduino mega2560 + ramps 1.4 + a4988 with marlin firmware for my DLP 3D printer. It has one stepper motor for Z axis movement, no endstops (willing to add it later) & haven't done any changes to marlin firmware. If anybody have solution for this please help. thanksby yogesh.dp - RAMPS Electronics
