Re: Sanguish development
Yes, .25 ohm = 2 A. I have 2A motors and it runs them just fine. I've run them at full 2A more than once. I currently run them at 1.5 amp to keep the motors cooler and I don't even have a fan on the...

My LCD1602 Ultrasonic Module DHT11 Shield
My LCD1602 Ultrasonic Module DHT11 Shield is compatible with the arduino mega R3. It can use LCD1602 display distance and temperature humidity value at the same time. For sharing(:P)

Uhm, Brian, could you look into this one: [reprap.org] ? I'd like to integrate Sanguish into Teacup, but I'm not sure wether the files you provide do what you intend them to do.

You can measure the thermistor at its connector to the board. The nominal value (100k) is at room temperature. Lower values at higher temperatures.

Well, I'm not quite sure either but it is what I intended. The power on pin on Sanguish only controls a FET that drives a relay that switches power to the stepper drivers. I left it as an output when...

Waste: Yes it could most likely be near the hot end if it's related to temp. What sort of thermistor have you got? An axial one (cylindrical, one lead goes in one side, and another lead goes in the...

Hi Annirak, Just a question about the L6470 Driver you mention (much) earlier in this thread Did you actually hook it up? Looking for code to use this driver with a Mega Thx Coolerooney

Hi everyone, I have bought a Melzi board and some 17HS8401 (1.8 A) stepper motors. To make the Melzi deliver 1.8 A current to the motors, I need to set the reference voltage of the stepper drivers...

When doing an image search for "A4988" i found several chips with markings similar to mine (example), so I guess I should be fine. I'm still interested in details about what this marking tells me though.

Been scrouging your schematics with a eagle eye looking for any potential issues that could ruin your next run: here's some comments: Enable Lines - seems each chips has a seperate Enable line to the...

Enable lines- agree, I mostly did that because routing was easier that way. I'll look at it. Current limit-agree, I'll put it on the list Enable line- not sure. isn't it safer to require +5V to turn...

Hard to say if what you read is good or not, as you didnt said exactly which points you read and what tool you read it with. I think you should read the voltage across sense resistors instead of...
View ArticleRe: tb6560 does not output much voltage
If you did in fact upped the torque to 100% (and just wrongly reffered to it as decay), then you need to say what is the motor coil resistance, and inductance e.g. datasheet or measured values at...
