Re: Test Suite to begin with a RepRap. - 14 years ago
Let's be honest that wall of text wasn't meant to do anything but discourage me. Either way you missed the arduino reference. The comparison lies in the fact that the arduino was created as a short cut way to teach people about microcontrollers. Just like an EE could say (and many DO say) that the arduino skips important steps and "prevents" newbies from learning, you could say that writing a sby attrezzopox - Controllers

@Lanthan > do you think the current variability of boards & configs would allow for practical automatization of config testing? Yes I do. The utility I'm suggesting would be used on arduino based hardware, I assume other micro-controllers would have to deal with the issue on their own. And I wouldn't consider the process "automated" in the sense that no one is at the controls. I would cby attrezzopox - Controllers
Re: Test Suite to begin with a RepRap. - 14 years ago
I assume for the first portion the end product would be a program that helps to verify all of your hardware actually works before you try to send gcode. A secondary goal might be to produce a usable pin-out/config file that a firmware package could use as starter values. The benefit is at least the basic parts of the printer would be known good. That and to break off a portion of the firmware thby attrezzopox - Controllers
Test Suite to begin with a RepRap. - 14 years ago
I searched half-heartedly for a way to test my RAMPS firmware step-by-step and came up empty handed. I was wondering if anyone had a good method for doing this already? A bit of test firmware that would start at the basics. Is the stepper moving, if not do this, is it moving now? If not do this. OK now that it's moving which direction? Trigger the x-opto, I see that it's high, move the x-carriageby attrezzopox - Controllers

At least there's that then... The torque in the motors lead me to believe they were enabled as well. I thought I corrected the code I was using but I'll double check. I KNOW I set the enable pin for the axis I'm using to high assuming that was enabled. Is there a pin that enables all of the drivers? The rectangle firmware seems to suggest in at least one arduino revision there was. I'll likelyby attrezzopox - Stepper Motors, Servo Motors, DC Motors

I have identified the coils. Thanks for the description btw, after looking at the pololu datasheet and reading your reply I realize I had them plugged in correctly. You should be able to see that in the youtube, they're plugged in correctly in that video. Moving on, I noticed the rectangle test was based on another arduino board so the pinouts were wrong. I thought I had it figured out when Iby attrezzopox - Stepper Motors, Servo Motors, DC Motors

I attached a datasheet the stepper motors I'm trying to use on my reprap. First things frist, the model number is 17pm-k005-k28vs. You may notice that they're not in the datasheet I attached, that's probably because they're custom pulls. I measured the resistance between unipolar and bypolar configured coils and they are 2.3 and 4.6ohms respectively. I'm trying to control them with a RAMPS 1.2by attrezzopox - Stepper Motors, Servo Motors, DC Motors
