change it to 250000 in config and PronterfaceQuote
Alexus12
..Try to set uart0.baud_rate 250000 in your config file, and change it in the Pronterface.
Can you move axes using display?

Theres 3 versions of sbase v1.1 and v1.2 and v1.2 with fixes, if he has the v1.2 without the fix then thats his issue

Would it be safe to put some small heatsink on the back of the drivers? Kind of like the small ones on pololu drivers, or would it short out something?Quote

Also what's with the heatsinks on the 8825's? Shouldn't they be on the (possibly too small) solder vias on the other side?
Yes, putting the heatsinks on the top is definitely very bad design, from somebody with no experience in this, who has not even cared to read the datasheet for the drivers ( or understands how they work ). This is the same attitude that caused the temperature problem.
arthurwolf : you are right,the heatsinks on the bottom of 8825 is better. But when the chip's temperature too high(up 70), the temperatue on the two side almost the same. Because on the bottom is harmful to Installation board , a big heatsinks on the top is useful.
Before we do this, we have read datasheet and get suggest from TI's engineer(we use drv8825 more than 10k/month not only on 3d board). We have tested, when use the heatsinks the temperature can low almost 5-8 degree than not use it on the same condition. If use fan can get better effect.
In fact we have careful deal with heat dissipation problem. on the pcb design the surface layer and the middle layer of the copper(GND),The area of the copper(GND) is as large as the plate.

I think you can, just use some thermal conductive pads so it wont short.Quote

I don't really have any such. I have some 3M 486MP tape and a bunch of the small heatsinks... I really don't think there is anything to short, but just wanted to hear it from someone who actually knows it for sureQuote

Bullied by which devs?Quote
Leafy1
I had been considering a real smoothieboard, but got sucked into this thread with the MKS promise and now I'm questioning if I even want to go to ANY board that uses smoothieware firmware after seeing the attitude of the devs. The only potential show stopper I have past being worried about being bullied by the dev is can end stop switches be disabled after homing? I use a 1/4" MIC-6 aluminum plate for my bed on my i3 and a prox sensor for my z stop. I have a G92 built into my post to go at the beginning of my g-code so I can set the prox sensor so the nozzle is 1.5-2mm off the print surface and then adjust my z level with software if it drifts over months time or if different filaments like different 1st layer heights. This works perfect in marlin, but I couldnt find anyone else doing it like this online so I figure its not a common way to do it and might not be supported universally, especially if something common sense like software end stops arent.

I hear ya as I purchased a machine using the Mightyboard and Sailfish 7.8 and hate the damn thing. I mean I am so detached I can't do any of the stuff I could do within Marlin.Quote
Leafy1
Probably. I know how marlin works it's safe, well documented and easy to work with. But being able to reconfigure without having to recompile with a text document on smoothie sure is appealing. Having two or more firmware options for the board and knowing one has the features I want makes it much more appealing. I'm not afraid to dick around and learn new things if they're better, if I wanted something that just worked I'd buy something closed source, pre built, and expensive. I just want to make sure when going into something that it does what I want the way I want it, which is what's holding me up from switching to s3d, I've got no problem dropping 150 bucks on a slicer but I want to test drive it first.

Can you explain to me how to measure to be sure? I do have a nice multimeter and know how to use it. I just don't know how to test for what you saidQuote
w3drk
Be careful, if I recall the vias under the drivers are "untented" meaning there isn't any solder mask insulating them. If those vias are part of the supply domain and your heat sinks make contact with them they could end up being live and potentially short to a grounded chassis, etc.
Odds are they are ground vias, but I'd measure to be sure.

I'll say Smoothieware has great potential. I really love the object-oritented approach.Quote

What are you talking about ?
Soft endstops are pretty much the only major feature Smoothieware is still missing. It's a planned feature, and the reason why we don't have it yet, is because it is not simple to implement *correctly*, and we do not implement things unless we implement them correctly.
Some folks have already taken a crack at it, and we'll eventually get to have it working, we just are not there yet.
I have no idea what you mean about bullying ...

Using heatsinks in conjunction with fans I get much better cooling at a potentially lower noise ration I do have a lot of small heatsinks (as mentioned), so might as well use themQuote
chris33
why not use fans to cool it better i was just going use a fan as i would any other board, have u got a probe set up and if yes what your using dintid
