Is it possible to use stock optical stops on my Da Vinci 2.0?

Karltinsly, i'm also upgrade to Ramp1.4.
How did you determine which wires are positive and negative on stepper motors?

They are are marked on the drivers and you can see the traces from the drivers leading to each pin of the connector on the mainboard. Thats how I did mine.

#define TEMP_SENSOR_0 1
#ifndef TEMP_SENSOR_1
#define TEMP_SENSOR_1 0
#endif
#define TEMP_SENSOR_2 0
#define TEMP_SENSOR_BED 1



Also make sure the board type is set to 33.

I have a very good cooking thermometer called a thermapen, but I couldn't figure out how to use it to measure surface temp. I do have a multimeter with a temp probe (which looks just like the glass bead thermistors our printers use). I guess I could tape it to the bed and maybe the hot end with some kapton tape. I'll give it a try tonight.

Can you recommend a good contact-type thermometer?

I bought a digital multimeter from harbor freight that also measures temp using a thermocouple. I also have a digital cooking thermometer that goes up to 600F that I got on Krogers cooking isle for a few bucks.

You are probably getting hot enough but the wrong temp is being reported. You also need a contact type thermometer as the IR type dont work well on reflective surfaces and that glass is reflective and your reported temp could be off by as much as 30 degrees. The hotend is also teally too small of a source to get an accurate reading on as well. I am not the only one here that will tell you relying on a non-contact thermometer is a bad practice and could cause more problems.

When I hooked up to the 300w bench supply, it did heat up to temperature. I think I'll order a 500W power supply and figure out how to mod it into the case.

The thermistors I'm using are these: http://us.banggood.com/Wholesale-Wareho … 05643.html

I'm using them successfully on my d-bot on both the v6 hot end and on the aluminum heatbed. Interestingly, I have the sensor type for the hot end set to 5 and the sensor type for the heatbed is set to 11. They seem to work very well, though.

I'm not sure what sensor type to use on the Da Vinci. Once I got the bed heating up, when it got to 60, the bed got as hot as 83C. I might just need to try different setting and see which comes closest, unless you have some ideas.

I just hooked up a 300W computer power supply that I use on my workbench, and got the same results. I set the temp to 60C, and the bed heated up to 53.8C and then stopped heating. So it's not the power supply.


What sensor type are you using in your firmware for the bed? Also 300/12=25 which means that is only 25 amps. The stock power supply is 30 amps. When I had mine I went up to a 35 watt to help with heating as I noticed the lights pulse to the PWM of the heater.

The RAMPS pulls more current on the bed heater than the stock board did. You a need at minimum 30 amps but more if possible.

i did not mention that upgrade since it was done before the RAMPS install and not part of that upgrade.
