Welcome to the SeeMeCNC Community

Hello all. Just wanted to stop in and say hi. I received my H1 and have it assembled. I am working with mach3 to get it printing. I was looking for help in set in up the motor travel and figured I better become a member. I am new to CNC and 3d Printing. I have been working with blender for 3 years I noticed No one is using this to make 3d modules. Blender is not the friendliest software to learn. It is also tricky to get measurements in blender units. I still like it for the power it offers in CGI and animation. I look forward to getting my H1 Printing. Thank You.

Welcome Nodak! You're in for a fun time learning all there is to 3D printing!

Thanks John.

I have been watching your youtube. I love the power of Mach. I built a Hot wire foam cutter last winter, Controlled with Mach3. I like that you can stop printing and resume. That is just cool. So Last night after some frustration with the TB6560 4 AXIS stepper driver I realized I was set up for 1/16th steps. I switch the dip switches to the 1/8 steps and it was close to jogging 1 inch increments. I noticed that when it was set to 1/16 steps the motors were much quieter and less resonating in to the machine. I am going to stay with the 1/8 steps. Tell I have some test prints.

I am also looking for recommendations on a nozzle controller.

I am also looking at the ramps kit at your indigo campaign. What are the benefits to ramps?

RAMPS is a 100% open-source hardware and software approach to controlling the printers. Also, it controls the axes, a hot-end, heated bed and fan, or two hot ends for dual extruders and heated bed. It is much more portable, however, it has it's limits. The polulu's aren't as forgiving at getting set up as the boards we supply for our mach setups. RAMPS is a bit more techie than a mach3 machine, but they both have their pros and cons. I like them both actually!

Thank John.

I ordered a velleman heat controller. After soldering it together it did not work . So trouble shooting started. I found the copper trace between pins 12 and 13 of the IC was shorted to pin 12 . Pin 12 was shorted to 5v all the time. I now have it working. Just a heads up for any one assembling a MK138. Be careful when soldering the IC. Make sure there is resistance between pin 10 and 12 of the IC.

I have seam to lost my files with the build instructions. I also am have trouble finding the docs on the web. Any one know ware I can find them? I was wiring my hot end when I figured out that the resisters could be wired in series or parallel.

The CNC board gave me lots of headache, you need to apply ghetto hacks to make it work right. RAMPS was much easier, didn't have to solder any components, just wires.

The RAMPS software is also way easier to configure and use than mach3.

The only reason the pololus "aren't forgiving" is because the seemecnc guys are shipping the wrong steppers with RAMPS.

Once I downgraded to the proper <2.0A steppers the pololus worked at a wider range of settings and gave me more torque which meant faster print speeds.

It sounds like you don't know what you are doing or talking about. I have a Sanguinololu with pololu drivers and the motors supplied by SeeMeCNC folks. No problems with the motors or drivers.

It will work but <2.0A steppers will generally provide more torque on RAMPS (depending on the steppper).
