    Re: Replace T-Slot for tooling plate?

    I just got the digital indicator and holding arm. It turns out the error in flatness is way beyond the requirement for PCB milling. At this moment, I only measure along the Y-axis. I think X-axis is...

    Re: Are all 1.5kw spindles the same?

    Sorry to bring up this old topic again. A 1.5KW motor will only produce 1.5KW power at full speed. At half speed, it's 750W, and so on. The price difference of those spindle motors is due to several...

    You may ask the seller for an upgrade. The specific spindle clamp (let's say 80mm) of your machine is the most important. Once you have it, you can use up to 2.2KW spindle motor. BTW, you need to...

    You can buy three normally-closed switches and wire them up. Make sure your BoB has 3 input pins left. I installed 3 switches and used them for homing. You may not need limit switches since limits...

    Despite of the hassles and troubles, $800 for a 800W water-cooled 3040 is a steal. IMHO, CNC router is unlike car or bike, you need to look into details in order to work flawlessly. My company owns...

    May I ask how much you paid for it? I've seen one very similar to yours. That machine is fine. It will do the job. BTW, I recommend car coolant for water pump. If you use tap water, you need to...

    Re: Replace T-Slot for tooling plate?

    That's a very good practice. I will order the dial indicator for sure. Using the indicator, shims and spoilboard seems to be the best solution for me. Thank you, guys. I know I come to the right...

    Re: Replace T-Slot for tooling plate?

    hi wizard,

    Thank you for the detailed information. I've heard of vacuum table, but I think I will use double tape first. BTW, I've seen someone who designed a holder for 2 toothbrush heads around...

    Re: Replace T-Slot for tooling plate?

    hi,
    Spoilboard is the first thing pop-upped in my head. Due to the unevenness of the low quality T-slots on my machine, I think the position where the spoilboard was made needs to be marked or...

    Replace T-Slot for tooling plate?

    Hello,

    My machine(1st image) is based on T-slots but I found the joint section of each T-slot may not have sufficient flatness for PCB milling. I am thinking abut ordering a tooling plate for...

    Re: Don't do business with this company

    As a Taiwaner, I'm sorry to hear about your story. Some people just don't have any idea of inner Mongolia. You should have mentioned China instead. I don't know what QT57 is, but I think the...
  13. Re: PCB: AccurateCNC A637 vs. Carbide3d Nomad vs Tormach PCNC 770 vs CNC Masters Baro

    Maybe it's a bit late to reply. If you want really good machine around 10~15k, I'd recommend Mits PCB Mill from Japan. Very reliable and accurate. It uses small camera for positioning, much better...
