    Re: Is there a hobby waterjet like a Wazer?

    The WAZER doesn't seem economical at all. If you look at their feed rate, it can cut (max) .1875" mild steel at .4 ipm. It consumes .33lb of garnet per minute at ~$1.1 per pound.

    Imagine a...

    Re: First EG mill

    My alignment setup on a 3600mm rail was almost identical; one question: I was only using it for a vertical plane as I couldn't find data for wire sag that I was confident in; I was able to find...

    Andrew,

    Thx for the reply.

    Yes I am tired of making cabinets. Mainly I am tired of dealing with people constantly changing their minds, contractors always demanding the moon yet don't even...
  6. Re: Considering selling DIY 5' x 10' router; looking for advice.

    As I suspected I have really limited the market that would be interested.

    I have no idea what kind of expectations I should have, but even if I could run it 5 - 10 hours a week that would...

    Re: New machine design collaboration

    Hey lcvette, I follow you in Instagram and noticed all the pics you have posted lately. Is this the Chinese mill being discussed in the thread? If so, will you be updating here?
  9. Considering selling DIY 5' x 10' router; looking for advice.

    Thanks in large part to CNCZone, over the past couple of years I built a 5' x 10' steel framed, profile linear rail, stepper driven CNC router. I have been using it in my cabinet business.

    Due to...

    Tom,

    Thanks for the response.

    I haven't checked for damage, but I wired a separate power supply @ 24.3v and put V+ to Com0 on connect. I connected V- on the power supply to my central ground...

  13. Re: Looking for Suggestions on Building a Shop

    Just checked. The world record for a line pump is ~2000m. So it's possible....but I wouldnt want to see how much it cost. Call Cherokee Pumping out of Atlanta (that's who I used to use) and ask them...
  14. Re: Looking for Suggestions on Building a Shop

    I used to own a concrete finishing company.

    First, mixing it yourself with bags is completely out of the question.

    Second, anything involving a pump truck isn't going to sniff 1/2 a mile. The...

    Re: My third build, all steel this time!

    Fluxion,

    Nice build. A couple of questions that I didn't see asked earlier.

    How did you align the long axis rails?

    And after alignment how did you locate the mounting holes accurately?

    Re: Heavy steel build, ATC, R&P, Servos

    Are you the guy that had DMM servos originally and replaced them with the Leadshine EL5? If so, I have seen several of your vids; nice machine.

    I have been eyeing the EL5's for a prospective...

    Re: Steel Gantry CNC Milling Machine

    Nice build. Posting to subscribe.

    +1 on profile linear rails; it would be a crime to save a few bucks considering the amount of work you have put into that beautiful frame.

    Ok, then you should be able to do it. If you have any experience with C or C++ that would be even better. The Arduino libraries are pretty straight forward, but you will need to know some programming...

    Since you have to ask if a micro controller is suitable, then I would first say this isn't exactly a beginner project for a micro controller. (depending on what skills you have)

    Re: 5' x 12' x 16" 5 Axis Router Build

    You need to tell us what the machine will be used for. Everything flows from that.

    Depending on what it is, 16" can be a lot of Z travel. Remember your Z acts as a lever. Relatedly, your gantry...
