Thanks. I guess i need to look for a better micro-controller.by changfrancis - Firmware - mainstream and related support
Hello all, I am exploring the 1/32 microstepping. I will like to know if Ramps V1.4 able to support a 1/32 stepper driver like or after we install the stepper driver to a RAMPS V1.4. I understand we need to set the MS1 MS2 MS3 to correct setting to enable 1/32 stepping. Does anyone know how do we do it on RAMPS ? Software or hardware method ? In Marlin Firmware, do we need to set any settinby changfrancis - Firmware - mainstream and related support
Yes. I noticed too. (You meant the white label that is on the print ?) I had re-connected them, thanks. Havent got a chance to print anything major yet. I had only been print square cube for testing . I am currently using a 12V 40W heater element for the printed bed. I noticed that it is not sufficient to keep the bed at 100degree. When i measure the voltage, it is at 12V. Hence, I am sure tby changfrancis - Firmware - mainstream and related support
I had successfully done my first print. Check up Up! forum for my post. My solution comes in 2 parts. First, I set marlin to Home Z at 140mm. Home at bottom. (Normally Reprap default home Z at 0mm, which Up! printer can't as there is a missing limit switch.) See attached Marlin Code. Second, use Pronterface software to manually shift the the bed until it just touch the extruder nozzle. Recordby changfrancis - Firmware - mainstream and related support
Hi reprappers, I wanted to print a cube of 150mm x 150mm x 150mm. I noticed that my print have a leaning tower problem. The product is tilted. I know the common solution is to tune the XYZ axis to a perfect square. But looking at the mendel design with so many parts that can create errors, is there a software way to correct the leaning tower problem ? I was think if the sli3r or marlin firmwareby changfrancis - General
Hi, I have attached the photo of the UP! printer internal. By default when unpowered, the Z-axis will be sitting on the bottom of the printer due to gravity. (about 140mm away from extruder head) The construction. - 140mm x 140mm x 140mm - All X Y Z axis uses 2GT belt and pulley system (no lead screw) - All X Y Z axis uses a linear rail to guide the axis - see attached pic for mech limit switcby changfrancis - Firmware - mainstream and related support

Hi, I am doing the same conversion too on Up! printer with the Ramps board. I had burnt my motherboard and chip recently. Currently I am using Marlin, Pronterface, Slic3r and Ramps 1.4 I had did some hardware change too. I noticed Ramps is a 12V system, all the heater and thermistor need to change to 12V system also. I guess we can home at the bottom limit switch but setting need to be madby changfrancis - Firmware - mainstream and related support
Thanks for the reply. I looked in to the code again. I found that there is a power saving mode in the configuration_adv.h of marlin firmware. //default stepper release if idle #define DEFAULT_STEPPER_DEACTIVE_TIME 60 set the 60 second to a very big number so that it cant cut the power supply Problem solved thank you.by changfrancis - RAMPS Electronics
Hi all, I am a newbie for reprap. I had just converted my Up! printer to a reprap I had installed a RAMPS 1.4 electronics, using Marlin firmware and Pronterface. I had some issue with my setup which I need the forum members help. Unlike Mendel lead screw, the setup of my Up! printer Z axis is belt drive. Basically Mendel X and Y axis working as a Z axis in Up! printer. I must constantly powerby changfrancis - RAMPS Electronics
