All the .cfg files are in /etc/redeem. If you see your printer in there, great! Otherwise you will need to build your own .cfg. To do this, make a copy of default.cfg and rename it to <your_printer_type>.cfg. Then make any changes you need. Next, I’d delete out any parts that you didn’t change so that your config stays clean. Finally, if you have any personalizations for your specific printer, create another file called “local.cfg” and put them in that.
Basically, it works like this: default.cfg is used to set all settings. “<your_printer_type>.cfg” is then used to override any settings in default.cfg. “Local.cfg” is then used to override any settings that your printer needs that’s beyond what is in “<your_printer_type>.cfg”.
Example: I have the same default.cfg as you. But I have a rostock_max.cfg that has the override settings for that type of printer (delta, arm lengths, etc). Finally, I blew up my ext1 circuit and had to do a mod to get my printer working again. That mod is in local.cfg because it only pertains to my specific printer, not all rostocks.
The setting you will want to override is “current_x = 0.5” for your “x” stepper. If it’s running hot, try “current_x = 0.3”. You will want to do this with each stepper (current_y, current_z, etc.) Restart Redeem after you make changes.
Veridico Cholo, Did you still use the Steps per mm value for the 1/16 micro step or did you recalculate for 256 steps when using setting number 8? I too am using 1/16 micro step. When I try either setting 4 or 8 my axis moves way too much for what is programmed. I am using the same micro step numbers and setting that I have used on this printer for a few years now but the replicape doesn’t apply them correctly for me.
Steps_per_mm (in the cfg) is calculated without regard to microstepping. Do the math for whole steps, the software will compensate for whatever microstepping you choose.
If you are using old settings from Repetier/Marlin/etc, you are likely off by a LOT.
Andy, Thanks for the info. So I need to divide all my setting by16 since my numbers were for 1/16 micro steps originally. That makes sense because when I called for a 1 mm move I moved about 16 mm. Thanks again.
Sorry, just realized it depends on how you are doing the calculation. Number for most printers will be between 3 and 6, if that helps. Depends on gearing of course.
Andy, I got it dialed in last night. I’m set on 8 and I took my original steps per mm that I used on my ramps and divided it by 16 (I was using 1/16 micro steps). Now I am dead on with movements. 1 mm = 1 mm, 10 mm = 10 mm, ect… I am very pleased with how quiet these boards are. I’ll be messing with speeds tonight to find where my limit is.
