    How to choose correct Beam Splitter for 50/50 output with sealed beam co2 laser? S vs P pole

    Been a while since I’ve done this. I think if laser is mounted Horizontally I need a P-pole and vertically an S-Pole, but I’m not 100% sure. Thanks in advance

    Has anyone used Cubloc Studio? How do i set an output?

    We purchased a CUSB-14R with a Cubloc CB280 Cpu, I downloaded the studio and I can set up an input with no issues in the ladder, but there is no operators for setting up an output or a delay for that matter. was going to use it to automate a door interlock so that the operator wouldn't have to...

    Boosting an Analog input signal

    I work on really old CNC/Laser systems and noticed that when I use my analog input of 0 to -8v that when the laser it is feeding loads the signal down quite a bit. -8v becomes about -2v. These two pieces of equipment do not normally work together, but I have every other function working...

    How do you feel about Wire Ferrules vs Regular Stranded wire connection?

    I do Field Service, so I fix a lot of machines by finding a loose connection. quite frequently it is a loose connection and more often then not one that has a ferrule. rarely do i find a loose wire that is stranded. Would really like to know everyone's opinion on this. "I am stuck on Band-Aid...

    Direct Logic 205 PLC controlling a stepper motor to be controlled by an Analog Voltage

    Looks like I got in over my Head, I had used Click PLC's before so thought I could handle this project. Goal: Use a capacitance sensor module that produces a 0-10V signal to determine position and maintain it. The sensor uses an Analog output where 1V = 1mm. If has an Analog Input used as a...

    Mirror Alignment on a Mazak New Turbo X48

    Friend of mine has a machine shop with one of these and asked if I could help him with it. I have worked on several different types of CO2 lasers but never a Mazak other than a simple Vacuum Leak. I only remember that Mazak was completely uncooperative in sharing any info at all. This was a...

    480 3 ph vs 208 3ph

    I work on industrial equipment most of which can be wired for either. What are the Pro's and Con's of each? Also I noticed that one of our systems has the Transformer that converts 480 to 208 right next to the Transformer as opposed to near the equipment 100' away. wouldn't it be easier to run...

    I have no experience with PLC's and have been tasked to automate some old equipment

    We Have several types of lapping machines I maintain that all work basically the same, I am thinking a PLC may be a good choice. Here is how basically every piece of equipment works: 1. Operator sets an old resettable mechanical Timer to desired cycle time from 10 seconds to 30mins or more. 2...

    Laser Exhaust duct Hose for Metal Cutting Lasers

    What material do you prefer? The Heavy black welding duct hose is too inflexible and comes apart to easy and the gray economy hose just doesn't hold up well. "I am stuck on Band-Aid brand, 'cause they are stuck on me"

    1" thick a36 steel plate amada FO3014

    Hello I'm going to be doing a test cut on 1" steel & would like to know what settings would be a good base line to start with. I've done 1/2" with no problem using the WACS head. What size nozzle should I be using? I have a 2.5mm WAC nozzle currently. I do have a cut condition for 1" but its...

    Do Industrial Mechanics need to pull permits to install new equipment and drops?

    I should know this, but I have never seen it written. Everywhere I have worked we have installed Sub-Panels and Drops on the fly to accommodate new equipment installation. Working at a new company and I don't want to draw attention to it by asking an inspector but I do want to know what the...

    amada fo315 nitrogen cutting nib on hole

    I get a tiny ball or bump when cutting with nitrogen. No matter the thickness of material or hole size. Its the start/stop point. I've tried different nozzle types, focus heights & speeds. I get a clean cut everywhere else. I'm currently cutting 16ga crs with N2 because of the amount of...

    Sealed CO2 Lasers 300w-500w

    We are thinking about upgrading one of our gas hogging V505 photon Lasers to a sealed beam laser. Where I used to work we had Coherent Diamond K-series (K250's) and Synrad Firestar F400, both would fit the bill for what we would use them for (Ceramic, scanning and light metal cutting). What...

    Fanuc C2000 DC PSU and RF units

    We have about 4 defective sets on our shelves collecting dust, from what I can tell by looking at them is it is usually the DC PSU that fails because I can see the same resistor components on a few of them blown open. I would love a schematic to these or even related ones so I can troubleshoot...

    Amada Orion Superpak Desiccant Change

    did a 5000 hr filter change and was looking at the 1000 hour kit and the sticker price was well over $2000. that seems obscenely high for desiccant and some orings. Has anybody rebuilt the cartridges themselves? I noticed their are two types of desiccant in each stage, a beige and a white...
